AdaptiveAnswer

Control whether or not an adaptive answering
strategy is used whereby an incoming call is
answered in multiple ways according to the list specified in the
AnswerRotary parameter.
For example, if adaptive answering is enabled and
AnswerRotary specifies ``fax data'', then an incoming call will
first be answered as fax using
ModemAnswerFaxCmd and then, if that fails, as data using
ModemAnswerDataCmd .
If the adaptive answer strategy is not enabled, then calls
are answered using the appropriate
ModemAnswer*Cmd parameter (normally
ModemAnswerCmd for unattended operation).
Note that the adaptive answer strategy depends on many factors
that limit its usefulness.
When calls are answered first as fax,
it typically only works with a Class 1 modem because it is
important that the sequence of operations related to answering
as fax be completed in a short enough time that a subsequent
answer for data be done before the caller times out and hangs
up the telephone
(for this reason
Class1RecvIdentTimer should be set to a value that is shorter than
FaxT1Timer .)
Also, note that it is sometimes necessary to arrange that the phone be
placed on-hook between successive answers; this can typically be
done by inserting the appropriate command at the start of the
second and subsequent
ModemAnswer*Cmd s.

AdminGroup

Tells PAM what user group is allowed to administer the fax server.
Only useful if the server is compiled with PAM enabled.

AnswerRotary

The sequence of answering techniques the server should
``rotate through'' when answer incoming calls.
Answering techniques are:

Name	Description
fax	answer a fax call
data	answer a data call
voice	answer a voice call
extern	use the vgetty application to answer a call
any	answer a call of any/unknown type

When a call is not answered succesfully, the server advances the rotary to the next specified answering technique. If AdaptiveAnswer is enabled, the server will try all the answering techniques for each incoming call. Otherwise, the rotary is advanced between unsuccessful phone calls. For example, if AdaptiveAnswer is disabled and AnswerRotary is ``fax data'', then the calls will initially be answered as fax until the first call is received that does not appear to be from a fax machine; after that calls will be answered as if they were from a data modem until the next unsuccessful call; after which they will one again be answered as fax. Only the first three techniques listed are used; any additional ones are (silently) ignored. See also AnswerBias .

AnswerBias

The index into the AnswerRotary list that the server should rotate the list to after each successful incoming phone call. List indices are numbered starting at zero. For example, if AnswerRotary is ``fax data'' and AnswerBias is 1, then after each successful inbound call, the next call will be answered as data.

AreaCode(S2

The local area code in which the facsimile modem resides. This value is passed to the dial string rules that are used, for example, to formulate canonical phone numbers for dialing (see DialStringRules below.)

CIDName

A string that identifies the caller's identity in any Caller-ID status messages or the called identity in any DNIS messages. The specified string is compared against any unrecognized status messages received from the modem before ModemAnswerCmd is sent to the modem. If there is a match, then the remainder of the message is returned as the ``caller name''. For example, for the ZyXEL U-1496 this parameter would be set to ``CALLER NAME: '' (note the trailing space). If more than one message matches, then the message remainders are concatenated. See also CIDNumber and QualifyCID .

CIDNameAnswerLength

An integer indicating the minimum number of characters in CIDName to be received when ModemAnswerCmd is sent to the modem irrespective of any RingsBeforeAnswer value greater than zero.  This allows the answering of calls which deliver CID/DID data but not RINGs. A value of zero for CidNameAnswerLength disables this feature.

CIDNumber

A string that identifies the caller's phone number in any Caller-ID status messages or the called number in any DNIS messages. The specified string is compared against any unrecognized status messages received from the modem before ModemAnswerCmd is sent to the modem. If there is a match, then the remainder of the message is returned as the phone number of the caller. For example, for the ZyXEL U-1496 this parameter would be set to ``CALLER NUMBER: ''. If more than one message matches, then the message remainders are concatenated. See also CIDName and QualifyCID .
The special CIDNumber value of "SHIELDED_DTMF" is used in conjunction with ModemRingResponse and CIDNumberAnswerLength. After executing ModemRingResponse, HylaFAX will expect DTMF data (usually DLE-shielded) for CIDNumber until CIDNumberAnswerLength is reached.  Note that if the modem is in voice mode to hear these DTMF digits, then it must be returned to fax mode in the ModemAnswerCmd.
For example, the following settings will cause HylaFAX to enter voice mode and go off-hook when a RING is detected.  It will then expect four DTMF digits (presumably for routing), and then it will return to fax mode and answer the call.

  ModemRingResponse:     AT+FCLASS=8;H1
  CIDNumber:             SHIELDED_DTMF
  CIDNumberAnswerLength: 4
  ModemAnswerCmd:        AT+FCLASS=1;A

CIDNumberAnswerLength

An integer indicating the minimum number of characters in CIDNumber to be received when ModemAnswerCmd is sent to the modem irrespective of any RingsBeforeAnswer value greater than zero.  This allows the answering of calls which deliver CID/DID data but not RINGs. A value of zero for CidNumberAnswerLength disables this feature.

ClocalAsRoot

Control whether operations that set the CLOCAL bit on the modem device special file are done with the effective user-ID set to the super-user or the ``fax'' user. By default such operations are done as the fax user, except under IRIX where they are done as the super-user (because IRIX disallows manipulation of CLOCAL by anyone but the super-user).

ContCoverCmd(S1

The command to invoke to generate a continuation cover page; see ContCoverPage and mkcover(8) .

ContCoverPage(S1

A template file to use in creating "continuation cover pages" . If this parameter is non-null, then the server will pass the filename to the command specified by ContCoverCmd to generate cover pages for outbound jobs that are continued after protocol errors. These cover pages identify the receiver and indicate that the document is a continued transmission. If this parameter is not specified or is null, then the server will not generate continuation cover pages. The specified pathname must be relative to the top of the fax server's spooling area.

CountryCode(S2

The local country code in which the facsimile modem resides. As for AreaCode , this value is passed to the dial string rules for use in formulating canonical phone numbers for dialing (among other things.)

DestControls(S1

An optional file containing rules for controlling parameters on a per-destination basis; see destctrls(5) The following parameters may be controlled with this mechanism: MaxConcurrentCalls , MaxDials , MaxSendPages , MaxTries , RejectNotice , SessionTracing , and TimeOfDay . If no DestControls parameter is specified, or if the controls file does not specify default values for these parameters, then any settings in the config file used by faxq(8) are used for default settings. Note that faxq automatically rereads the contents of a DestControls file if it is modified while the server is running.

DeviceMode

The file protection mode that the server should set for the modem device file. Note that this value is given in octal. The default value of 0600 implies that only the facsimile user (usually uucp ) can access the modem. See also chmod(2) .

DialStringRules(S2

The pathname of the file that holds the rules for processing user-specified dial strings; c.f. dialrules(5) . The specified pathname must be relative to the top of the fax server's spooling area; e.g. etc/dialrules .

DistinctiveRings

Modern distinctive ring support on most modems indicates the ring cadence rather than the older style of ``RING1'', ``RING2'', etc.  To indicate the ring cadence, DRingOn and DRingOff values are presented by the modem to the faxgetty process.  The modem indicates the entire cadence between ``RING'' indications Like this:

  RING
  DROF=40
  DRON=8
  DROF=4
  DRON=8
  RING

The corresponding DistinctiveRings parameter for this ring cadence would be:

  DistinctiveRings:  F-8-4-8

where ``F'' tells the faxgetty process that the ring cadence is for a facsimile (``V'' for voice and ``D'' for data), and the other values describe the ring cadence with leading and ending DRingOff values ignored.  Multiple ring cadences are indicated by delimiting them with commas in this fashion:

  DistinctiveRings:  V-20,F-8-4-8,D-4-2-4-8

DRingOff

A string that identifies the ``off'' value in any distinctive ring cadence, for example ``DROF=''. See also DRingOn and DistinctiveRings .

DRingOn

A string that identifies the ``on'' value in any distinctive ring cadence, for example ``DRON=''. See also DRingOff and DistinctiveRings .

DynamicConfig

The pathname of the optional shell script, e.g. ``etc/localid'', that makes dynamic configuration changes, i.e., to LocalIdentifier, based on CIDName, CIDNumber, and device ID.  The script is passed those three values as the first, second, and third parameters ($1, $2, $3), respectively when answering an incoming call.  The script can then perform local processing as desired to send on standard output the configuration items to change in a ``parameter:value'' format, i.e. ``LocalIdentifier: +1.800.555.1212''.  If there are multiple parameters to be changed, then each item must be on its own line. This is commonly used to dynamically alter the local identification of systems which use DID/DNIS, but it can also be used to allow different modem configurations for different senders. Note that this script must be marked as executable by the faxgetty process.

FAXNumber

The phone number associated with the facsimile modem. This string is used to generate the Transmitter Subscriber Identification (c TSIc ) and Caller Subscriber Identification (c CSIc ) information passed to remote machines--unless the LocalIdentifier parameter is explicitly set. The FAXNumber is also used to name the session log file where information for incoming phone calls is recorded; see hylafax-log (5). If this phone number is not a fully qualified number the values of AreaCode and CountryCode are used to generate the transmitted CSI and TSI.

InternationalPrefix(S2

The string to use to place an international phone call. In the United States, this is ``011''. This string is passed to the dial string rules.

JobReqBusy

The delay in seconds to wait before retrying a job whose dialing attempt failed with a ``BUSY'' status result.

JobReqDataConn

The delay in seconds to wait before retrying a facsimile job whose dialing attempt failed because a data modem answered the phone.

JobReqNoAnswer

The delay in seconds to wait before retrying a job whose dialing attempt failed with a ``NO ANSWER'' status result.

JobReqNoCarrier

The delay in seconds to wait before retrying a job whose dialing attempt failed with a ``NO CARRIER'' status result.

JobReqNoFCon

The delay in seconds to wait before retrying a facsimile job whose dialing attempt failed because the initial facsimile protocol handshake failed (i.e. no ``+FCON:'' result was received from a Class 2/2.0 modem).

JobReqOther(S2

The delay in seconds to wait before retrying a job that failed for a reason not already covered by one of the Job* parameters.

JobReqProto

The delay in seconds to wait before retrying a facsimile job that failed because of a fax protocol error.

GettyArgs

A string that indicates whether or not the server should invoke the getty(8) program in response to an incoming call from a data modem. If the string value is not null, then it is interpreted as a set of arguments to pass to the getty program. Before supplying the arguments, the string is first scanned for ``%''-escape sequences: any appearance of ``%l'' is replaced with the tty name and any appearance of ``%s'' is replaced with the serial port speed (in decimal). The ``%'' character can be specified with ``%%''. If the GettyArgs parameter is not specified in the configuration file or if the string value is null, then data connections will be rejected. Note that in addition to the specified command line arguments, the getty program is invoked with its standard input, output, and error descriptors directed to the controlling tty device.

LocalIdentifier

The local station identification string to use when transmitting TSI and CSI strings (see FAXNumber above). NB: while this string may contain any printable ASCII characters; beware that "CCITT T.30" specifies a restricted character set and some fax modems and machines may reject or not display  non-conforming strings. If the local identifier is not specified, a canonical form of the FAXNumber is used instead.

LockDataCalls

Hold the UUCP lockfile during the time an inbound data call is processed by the external getty program. If this is disabled then the lockfile will be removed just before the getty program is invoked. Note however that doing this introduces a race condition whereby an outbound program may sneak in and take control of the modem after the inbound call has been accepted, but before the getty program has started up and installed it's own lockfile.

LockVoiceCalls

Hold the UUCP lockfile during the time an inbound data call is processed by the external voice getty program. If this is disabled then the lockfile will be removed just before the voice getty program is invoked. Note however that doing this introduces a race condition whereby an outbound program may sneak in and take control of the modem after the inbound call has been accepted, but before the voice getty program has started up and installed it's own lockfile.

LogFacility(S2

The symbolic name for the syslog(3) facility to use when logging error messages and informational/debugging messages requested through the ServerTracing parameter. The list of facility names is standardized; it can be found in the system include file <syslog.h> ; comparisons are case-insensitive.

LogCalls

Log all incoming calls into xferfaxlog as CALL records.  This allows a quick check of all incoming calls, regardless of fax completion or not in a unified manner with other fax logs.

LogFileMode

The file protection mode that should be used when creating files to hold session logs. Note that this value is given in octal. The default value of 0600 implies that the log files are not generally accessible, which is important if sensitive information such as calling card access codes are logged. If log files are to be publicly accessible, this value may be set, for example, to 0644. See also chmod(2) .

LongDistancePrefix(S2

The string to use to place a long distance phone call. In the United States, this is ``1''.

MaxConcurrentCalls(S1

The default value to use for the maximum number of jobs for the same destination that are processed concurrently. Note that each job is processed with a separate phone call; job batching is not currently supported. Thus this parameter defines the maximum number of concurrent phone calls to the same destination. Unless all of your fax destinations have multiple fax lines using the same fax number per destination then MaxConcurrentCalls is probably best left as the default of 1 and exceptions should be accomodated by the DestControls file.

MaxConsecutiveBadLines

The maximum number of consecutive erroneous rows of image data that the server will receive before it deems a page to have unacceptable copy quality. Setting this parameter to zero causes the server to not check the quality of received facsimile. Facsimile received with error-correction do not have copy quality checking performed. See also PercentGoodLines .

MaxDials(S1

The default value for the maximum number of times the server will place a call for an outbound job. This value may be overridden by rules in the DestControls file. See also MaxTries .

MaxRecvPages

The maximum number of pages the server will accept in a received facsimile before it aborts the session.

MaxSendPages(S1

The default value for the maximum number of pages the server will permit in a transmitted facsimile. Outbound jobs that exceed this limit are rejected. This value may be overridden by rules in the DestControls file.

MaxSetupAttempts

The maximum number of times a (Fx server program will attempt to initialize a modem before considering it ``wedged''.

MaxTries(S1

The default value for the maximum number of times the server will attempt to communicate with a remote site. Note that for a call to be counted against this limit, carrier must be established; this is in contrast to the value of MaxDials which limits the number of calls that will be placed on behalf of a job. This value may be overridden by rules in the DestControls file. See also MaxDials .

ModemGroup(S1

Define a logical name for a set of modem devices. This parameter can be used to define a name that clients can use to refer to a collection of modems. The syntax is ``<name>:<regex>'' where <name> is the name for the group and <regex> is a regular expression that faxq(8) matches against known modems. Thus for example, the default modem to use for a job, any , is defined as ``any:.*''. This parameter may be specified multiple times to define multiple modem classes. Modem classes may overlap. The actual set of modems in a modem class that are considered for use may vary based on which modems are believed to be ready for use.

ModemPriority

The scheduling priority to use for a modem. Priority values are in the range 0 to 255 with lesser values signifying higher (more desirable) priority. The (Fx scheduler process assigns the highest priority modem that is ready for use when scheduling an outbound job.
If multiple available modems in a job's selected ModemGroup have the same ModemPriority value, then the (Fx scheduler assigns jobs to them in a round-robin fashion.

NoAnswerVoice

Whether or not to disable the answering of calls indicated as voice (e.g. by DistinctiveRings ).

NoCarrierRetrys

The number of times to redial a phone number after receiving a ``NO CARRIER'' result code when the number has not been successfully dialed before. In normal operation the fax server will treat this result code to mean that a facsimile modem/machine did not answer the phone and reject the transmit job. This is done to avoid repeatedly dialing wrong phone numbers and depends on the modem distinguishing between no carrier and no answer. However, some modems are not capable of reliably distinguishing between no carrier and no answer, or when instructed to do so do not identify a busy signal correctly. For these modems one may find it necessary to increase the value of this parameter to compensate. It is strongly recommended, however, that this value not be set to a large number.

ModemReadyState

Define the state transmitted to the (Fx scheduler process each time a modem is made ready by a faxgetty process. State is one of: ``R'' (ready for use), ``B'' (busy), or ``D'' (down). The modem state can be used to control whether or not modems are assigned to outbound jobs. A modem's state is initially set to ``R'' (ready). Modem state can be dynamically changed with the faxstate(8) program or by setting this configuration parameter with the faxconfig(8) program.

ModemRingResponse

This can be used to cause the command defined by ModemRingResponse to be sent to the modem after hearing at least ModemRingsBeforeResponse RINGs in order to receive DID-DTMF data, for example.

ModemRingsBeforeResponse

This defines the minimum number of RINGs that must be heard before ModemRingResponse is first sent to the modem.

NotifyCmd(S2

The command to invoke to notify a client of a job status change; see notify(8) .

PageChop(S1

Whether or not to automatically truncate trailing whitespace on pages of outbound facsimile (when possible). If page chopping is enabled, then pages with at least PageChopThreshold trailing whitespace on a page will be transmitted as a ``short page'' if the receiver is capable of accepting variable-length pages. The possible values are: ``last'' to enable chopping of the last page of each document, ``all'' to enable chopping of all pages, or ``none'' to disable page chopping.

PageChopThreshold(S1

The minimum amount of trailing whitespace that must be present on a page before page chopping will be attempted; see PageChop . Note that this value is specified in inches.

PCL2FaxCmd(S1

The command to invoke to convert a HP-PCL document submitted for transmission to TIFF/F, suitable for transmission (for future use).

PercentGoodLines

The minimum percentage of good rows of image data required for a received facsimile page to be deemed to have acceptable copy quality. Setting this parameter to zero causes the server to not check the quality of received facsimile. Facsimile received with error-correction do not have copy quality checking performed. See also MaxConsecutiveBadLines .

PollLockWait

When polling for the presence/removal of a UUCP lockfile, the time (in seconds) to wait between checks. Lockfile polling occurs to ensure the fax server doesn't collide with another process using the modem.

PollModemWait

The time (in seconds) to wait between checks for a modem to become ready for use. Modem polling occurs when a modem fails to reset cleanly.

PriorityScheduling

Indicates whether the (Fx scheduler should utilize available priority job scheduling mechanisms to enhance realtime execution, particularly with Class 1 configurations on older or slower systems.
Currently PriorityScheduling is available for IRIX, SVR/4, HP-UX, and POSIX-compliant (i.e. Linux) operating systems.  The default value varies to maintain traditional (Fx behavior.  On IRIX, SVR/4, and HP-UX systems where the configure script detects one of the functions schedctl(), priocntl() or rtprio() the default is true. The only other supported priority mechanism is POSIX sched_setscheduler(), which is used on Linux, OpenServer and possibly other systems.  On such systems, as well as on systems where no priority scheduling mechanism exists, the default is false."

PS2FaxCmd(S1

The command to invoke to convert a (Ps document submitted for transmission to TIFF/F, suitable for transmission; see ps2fax(8) .

QualifyCID

A string that specifies whether or not Caller-ID information and/or DNIS information should be checked against an access control list before accepting an inbound call. If QualifyCID is non-null and there is Caller-ID or DNIS service, then only calls with data matching numbers identified in the file specified by this string (typically etc/cid) will be accepted; see cid(5) . If QualifyCID is not specified in the configuration file, or the value is null, then all incoming calls will be answered. Note that Caller-ID screening and DNIS routing are only available when this service is enabled on the phone line and the modem is capable of presenting Caller-ID status or DNIS data information to the host. The CIDNumber and CIDName parameters must also be setup to reflect the manner in which the modem returns Caller-ID status or DNIS data information to the host.

QualifyPWD

A string that specifies whether or not the identity of calling facsimile machines should be checked against an access control list before receiving facsimile. If QualifyPWD is non-null, then only messages from facsimile machines identified in the file specified by the string (typically etc/passwd) will be accepted; similar to QualifyTSI.

QualifyTSI

A string that specifies whether or not the identity of calling facsimile machines should be checked against an access control list before receiving facsimile. If QualifyTSI is non-null, then only messages from facsimile machines identified in the file specified by the string (typically etc/tsi) will be accepted; see tsi(5) . If QualifyTSI is not specified in the configuration file, or the value is null, then all incoming facsimile messages will be accepted.

RecvDataFormat

The data format (compression scheme) to write received facsimile data when copy quality checking is performed on the host. (When copy quality checking is not done by the server, for example when error correction protocol is used, the received facsimile data is written exactly as it is received from the modem.) The format may be one: ``1-D MH'', ``2-D MR'', ``2-D MMR'', or ``adaptive''. An ``adaptive'' format causes the received data to be written using the data format negotiated by the sender and receiver. Note that while 2-D MMR is the most space-efficient data format the resultant file may not be viewable (certain commonly used programs do not properly read multi-strip TIFF with 2-D MMR data).

RecvFileMode

The file protection mode that should be used when creating files to hold incoming facsimile. Note that this value is given in octal. The default value of 0600 implies that only the facsimile user can read received facsimile. If incoming facsimile are to be publicly accessible, this value may be set, for example, to 0644. See also chmod(2) .

RingData

A modem status string that identifies that an incoming call is for data use. This string should be set when a phone line has been setup with distinctive ring service. See also RingFax and RingVoice .

RingExtended

An identifier which matches the initial portion of an extended RING message sent by the modem to relay CID and/or DNIS data instead of sending it formatted on separate lines.

RingFax

A modem status string that identifies that an incoming call is for facsimile use. This string should be set when a phone line has been setup with distinctive ring service. See also RingData and RingVoice .

RingsBeforeAnswer

The number of rings to wait before answering the phone. If this value is set to 0, then the phone will only be answered in response to an explicit answer command; see faxanswer(8) .

RingTimeout

If a ring is heard and the call is not answered, the time in ms to wait before reinitializing the modem for the next call.

RingVoice

A modem status string that identifies that an incoming call is for voice use. This string should be set when a phone line has been setup with distinctive ring service. See also RingData and RingFax .

RTNHandlingMethod

Specifies how to react to RTN signal, received from the remote; one of ``Retransmit'', ``Giveup'' and ``Ignore''. ``Retransmit'' assumes that the page is not sent succesfully if RTN signal has been received. HylaFAX will make up to 2 additional attempts to send the page, decreasing signalling rate and retraining. If RTN is still there, it will place up to 2 additional calls. So if the remote always respond with RTN, the page will be send 9 times. Although this algorithm comply with T.30 specs and was originally implemented by Sam Leffler as the only possible choice, real fax machines behave completely different. There is a non-written rule among fax developers, that RTN means ``over and out'' -- hang up immediately and never try to send the same page to the same destination again. That is because RTN usually indicates problems with flow control, incorrectly encoded T.4 data, incompatibility between local and remote equipment etc., but very rarely is caused by the real noise on the line. This ``over and out'' behaviour can be activated by ``Giveup'' value. There is also third option, not so radical as ``Giveup''. Yes, we will never retransmit the page, but we can try to send the next page, and let the remote to decide what to do (accept our decision or hang up). Thus one page will (or will not) be missed but we have a chance to successfully send all other pages. This behaviour can be activated by ``Ignore'' value.

SaveUnconfirmedPages

Whether or not to save a received facsimile image page if the sender disconnects without sending the post-page message, without hearing our message confirmation, without retraining as requested, or otherwise breaks fax protocol following such pages for which the sender should not have a ``receipt confirmation''.

SendFaxCmd(S1

The command to use to process outbound facsimile jobs; see faxsend(8) .

SendPageCmd(S1

The command to use to process outbound pager jobs; see pagesend(8) .

SendUUCPCmd(S1

The command to use to process outbound UUCP jobs. This parameter is not currently used, it is for future development.

ServerTracing(S2

A number that controls the generation of tracing information by a server when not actively sending or receiving facsimile. Tracing is divided into areas that are individually controlled. To enable tracing of multiple areas of operation, the flag associated with each area should be bit-or'd to form the value for this tag.

Flag	Area	Description
1 (0x00001)	Server Operation	queue management and general operation
2 (0x00002)	FAX/IXO Protocol	T.30 facsimile protocol or IXO/TAP protocol
4 (0x00004)	Modem Operations	modem hardware manipulation
8 (0x00008)	Modem Communications	comands passed between host and modem
16 (0x00010)	Timeouts	timer operations
32 (0x00020)	Modem Capabilities	modem capabilities
64 (0x00040)	HDLC Frames	binary T.30 HDLC frames
128 (0x00080)	Binary Modem I/O	binary communication between host and modem
256 (0x00100)	Server State Transitions	server program state transitions
512 (0x00200)	Queue Management	job queue management
1024 (0x00400)	Copy Quality	copy quality checking of received facsimile
2048 (0x00800)	Job Management	low-level job management
4096 (0x01000)	IXO Protocol	low-level IXO protocol
8192 (0x02000)	Config File Parsing	unknown configuration file parameters
16384 (0x04000)	FIFO Messages	inter-application messages
32768 (0x08000)	Modem State Transitions	modem state changes (down, busy, ready)
65536 (0x10000)	Dial Rules	dialstring rules parsing and execution
131072 (0x20000)	Docq Changes	document reference handling
 .5

For example, to enable tracing of server operations and protocol operations, a value of 1+2=3 should be specified. NB: tracing timeouts and/or binary modem I/O can adversely affect the operation of the fax server; enabling these areas should be done with extreme care. Server tracing is directed to syslog(3) using the facility specified with the LogFacility configuration parameter. Note that syslogd(8) must be configured to capture facility.info , facility.debug , facility.warning , and facility.err messages. See hylafax-log (5) for a description of the logged messages.

SessionTracing(S2

A number that controls the generation of tracing information by a server while sending or receiving facsimile. The number is interpreted identically to ServerTracing. Note that session tracing is placed in log files in the log subdirectory; see hylafax-log (5) for more information.

SpeakerVolume

The volume level that the in-modem speaker should be adjusted to while in command mode. The possible values are:

Value	Description
Off	silent
Quiet	almost inaudible
Low	tolerable in privacy
Medium	loud enough to hear in the next room
High	intolerable
 .5

Note that the speaker is always turned off once carrier is established. Also beware that some modems support fewer volume settings; see ModemSetVolumeCmd .

TagLineFont

The filename of the font to use in imaging "tag lines" across the top of each transmitted page. Fonts must be stored in the Portable Compiled Font (c PCFc ) format used by the X11 Window System. Filenames are specified relative to the root of the spooling area; e.g. etc/lutRS18.pcf. If no font is specified, if a null filename is specified, or if the specified font file is not readable, then tag lines will not be generated. See also TagLineFormat .

TagLineFormat

The format string to use when imaging "tag lines" across the top of each transmitted page. This string may include escape codes that cause various items to be interpolated into the imaged tag line. Any escape code supported by strftime (3C) may be used as well as the following server-implemented codes:

Escape	Description
%%d	destination phone number
%%i	job identifier
%%j	user-specified job tag
%%l	LocalIdentifier or canonicalized FAXNumber
%%m	sender's electronic mail address
%%n	canonicalized FAXNumber
%%p	current page number of session
%%P	current page number of job
%%r	receiver's name
%%s	sender's name
%%t	total pages in session
%%T	total pages in job
%%%	``%''

In addition, the format string may indicate that text is to be centered in multiple equal-sized fields by separating text with ``|'' characters. For example, ``a|b|c'' would cause the tag line to be broken up into three equal-sized areas with the strings ``a'', ``b'', and ``c'' centered within each region. The default tag line format string is ``From %%n|%c|Page %%P of %%T''. The differences between the %%p or %%P and the %%t or %%T options are noticed when a fax job is retried after an incomplete attempt and only the previously unsent pages are then queued in a successive session. See also TagLineFont .

TIFF2FaxCmd(S1

The command to invoke to convert a TIFF submitted for transmission to TIFF/F, suitable for transmission; see tiff2fax(8) .

TimeOfDay(S1

The default time-of-day restrictions to apply to outbound jobs. Outbound jobs will be processed only during the specified time. Any jobs submitted outside this time period will be held until the start of this time. The syntax for time-of-day restrictions is designed to be compatible with the syntax used by the UUCP software. The following BNF describes the syntax:

   Syntax = tod ["," tod]       tod = <days><timerange>      days = "Any" | "Wk" | <dayname>+ | nothing   dayname = "Sun" | "Mon" | "Tue" | "Wed" | "Thu" | "Fri" | "Sat" timerange = <start> "-" <end> | nothing     start = <24hrtime>       end = <24hrtime> 24hrtime = {0-9}{0-9}{0-9}{0-9}   nothing =

where start and end are 24-hour times, day names can be either 2- or 3-characters, and a null day or time specification means any time or day. White space and other syntactic sugar may be freely inserted between tokens but may not be inserted between 24-hour times in the time range. This value may be overridden by rules in the DestControls file.

Use2D(S1

Control the use of 2D-encoded data for transmitted facsimile.

UUCPLockMode(S2

The file protection mode that should be used when creating UUCP lockfiles. Note that this value is given in octal.

UUCPLockDir(S2

The pathname of the directory in which UUCP lockfiles are to be created.

UUCPLockTimeout(S2

The time in seconds to wait before removing a stale UUCP lockfile (i.e. a lockfile whose owner does not appear to exist). If this value is set to 0, then the fax server will never remove a stale lockfile.

UUCPLockType(S2

A string that specifies the type of UUCP lockfile to create. The string may be one of ``ascii'' or ``binary'' depending on whether the process-ID of the lock owner is written to the file as an ascii string or as a binary value, respectively. In addition, two prefixes may be used to control the format of the lock filename. If the type string is prefixed with a ``+'', then SVR4-c style filenames are generated using the major device number of the tty device and the major and minor device numbers for the filesystem on which the tty device resides. If the type string is prefixed with a ``-'', then any upper case letters in the device part of the lockfile name are converted to lower case letters; for example, ``LCK..ttyA01'' is converted to ``LCK..ttya01''. This upper-to-lower case conversion is useful for systems such as SCO where the convention is to name devices with upper-case letters, but create lockfiles with lower-case letters.

VGettyArgs

A string that indicates whether or not the server should invoke a voice getty program in response to an incoming voice call. If the string value is not null, then it is interpreted as a set of arguments to pass to the vgetty program. Before supplying the arguments, the string is first scanned for ``%''-escape sequences: any appearance of ``%l'' is replaced with the tty name and any appearance of ``%s'' is replaced with the serial port speed (in decimal). The ``%'' character can be specified with ``%%''. If the VGettyArgs parameter is not specified in the configuration file or if the string value is null, then voice connections will be rejected. Note that in addition to the specified command line arguments, the vgetty program is invoked with its standard input, output, and error descriptors directed to the controlling tty device.

WedgedCmd(S1

The command to invoke when a modem is deemed ``wedged''; see wedged(8) .

ModemAnswerCmd

The command to answer the phone.
If possible, this command should generate a result string that
identifies whether the incoming call is from a facsimile, voice,
or data modem.
Typically this auto-detection is configured ahead of time; e.g.
for Class 2 modems with the ``AT+FAA=1'' command.
The following table describes how the result codes are interpreted by
the facsimile server.

 .5
Result String Default Class 1 Class 2 Class2.0


CONNECT FAX Fax - - - -


CONNECT Data Unknown - -


NO ANSWER No Answer - - -


NO CARRIER No Carrier - - -


NO DIALTONE No Dialtone - - -


ERROR Error - - -


FAX Fax - - -


DATA Data - - -


+FCON - - Fax Fax


+FCO - - Fax Fax


+FDM - - Data Data


+FHNG: - - Error Error


VCON - - Voice Voice




  The ``Default'' column indicates the interpretation made for the


result string in either class 1 or 2 unless explicitly


overridden.


The ``Class 1'' column indicates result strings handled specially


for modems operating in class 1, the


``Class 2'' column indicates special handling for modems


operating in class 2, and the ``Class 2.0'' column indicates


special handling for modems operating in class 2.0.


  Unknown

 entries imply that interpretation is based on the way in which the


call was answered; if answering is done for an explicit call type,


that type is assumed, otherwise a Fax call is presumed.

ModemAnswerDataBeginCmd

The command to send to the modem once a data
connection has been established.

ModemAnswerDataCmd

The command to explicitly answer the phone for a data connection.
This command must generate a result string that
identifies the incoming call is from a data modem.
If this parameter is not specified or is null, then the value of
ModemAnswerCmd is used instead.
See also
AdaptiveAnswer and
AnswerRotary .

ModemAnswerDialCmd

The command to explicitly answer the phone for a dialed connection.
This command must generate a result string that
identifies the incoming call is from a facsimile modem.
If this parameter is not specified or is null, then the value of
ModemAnswerCmd is used instead.

ModemAnswerFaxBeginCmd

The command to send to the modem once a facsimile
connection has been established.

ModemAnswerFaxCmd

The command to explicitly answer the phone for a facsimile connection.
This command must generate a result string that
identifies the incoming call is from a facsimile modem.
If this parameter is not specified or is null, then the value of
ModemAnswerCmd is used instead.
See also
AdaptiveAnswer and
AnswerRotary .

ModemAnswerVoiceBeginCmd

The command to send to the modem once a voice
connection has been established.

ModemAnswerVoiceCmd

The command to explicitly answer the phone for a voice connection.
This command must generate a result string that
identifies the incoming call is for voice.
If this parameter is not specified or is null, then the value of
ModemAnswerCmd is used instead.
See also
AdaptiveAnswer and
AnswerRotary .

ModemAnswerResponseTimeout

The maximum time, in milliseconds, to wait for a response from
the modem after sending
ModemAnswerCmd .
Note that you may want to shorten this value when using the
server-based adaptive answer strategy; see
AdaptiveAnswer .

ModemATCmdDelay

A delay, in milliseconds, that should be performed before each
``AT'' command string is sent to the modem.

ModemBaudRateDelay

The amount of time, in milliseconds, to pause after setting the
baud rate on the serial line.
This is only needed for hosts and modems (such as USRs) where
setting the serial line parameters does not take effect immediately.

ModemCommaPauseTimeCmd

The command to set the time,
in seconds, that the modem should pause when encountering
a ``,'' modifier in the dialing string.

ModemDialCmd

The command to place a phone call.
The string is assumed to be suitable for use
as a parameter to the
sprintf (3S)
function; so the ``%'' character should be escaped as ``%%''.
The dial command must include a single ``%s'' where the number
that is to be dialed is to be substituted.
Facilities such as tone or pulse dialing, outgoing prefixes
to route though a PBX,
and so on should be included in the
dialing command string.
It is also important that, if possible, a trailing ``@''
symbol should be included so that the modem
returns result codes that distinguish between no answer and no carrier.
Use of the ``@'' permits the server to reduce the probability
that a wrong number is continually redialed.
If the modem does not support this facility, then it may be
necessary to raise the number of retries done when a
``NO CARRIER'' result is returned.

ModemDialResponseTimeout

The maximum time to wait, in milliseconds, for a response from
the modem after sending
This value should be longer than the timeout programmed into the
modem through the
ModemWaitTimeCmd parameter.
This additional server-based timeout is provided to guard against
modems that can ``lock up'' when dialing the telephone.

ModemDTRDropDelay

The time, in milliseconds, to pause between placing
DTR
OFF and
DTR
ON while resetting a modem.  This value should be at
least equal to the time-value of the analogous S-register,
usually S25.

ModemEchoOffCmd

The command to disable echoing of commands sent to the modem.

ModemFlowControl

The type of flow control to use between
DTE
and DCE;
one of ``NONE'', ``XONXOFF'' and ``RTSCTS''.
This value is used to select the string sent to the modem
to initially establish
DTE-DCE
flow control; one of
ModemNoFlowCmd ,
ModemSoftFlowCmd ,
and
ModemHardFlowCmd .
The current flow control setting is also used to select the
appropriate flow control command to send to the modem when
the software switches to Class 1, 2, or 2.0; see
Class1HFLOCmd ,
Class1NFLOCmd ,
Class1SFLOCmd ,
Class2HFLOCmd ,
Class2NFLOCmd ,
and
Class2SFLOCmd .
The server supports both software and hardware flow control
for Class 1, Class 2, and Class 2.0 modems.
Whether to use hardware or software flow control depends
on the capabilities of the modem
and the host hardware and operating system.
Communication rates above 9600 baud often require that hardware
flow control be used for reliable
DTE-DCE
communication.
However, beware that many modems only support software
flow control when sending or receiving facsimile.
Note that modems usually support software flow control even
if they have no explicit AT-command to activate it; in this case
it is switched on when the modem enters fax mode, having
AT+FCLASS=... from DTE.

ModemFrameFillOrder

The bit order to expect for received
HDLC
frames and to use when formulating
HDLC
frames to send.
This value may be either
LSB2MSB
when bits are ordered from least-significant-bit to
most-significant-bit (as in the
CCITT
specification) or
MSB2LSB
when bits are ordered in the reverse direction.

ModemHardFlowCmd

The command to setup hardware (RTS/CTS)
flow control between
DTE
and
DCE.

ModemMinSpeed

The minimum acceptable signalling rate for transmitting facsimile
page data.
Possible values are: 2400, 4800, 7200, 9600, 12200, and 14400.

ModemMfrQueryCmd

The command to send to the modem to get the manufacturer
identification string.
If this parameter is not set, then it is initialized
to ``AT+FMFR?'' for Class 2 modems, or
to ``AT+FMI?'' for Class 2.0 modems, or
to ``ATI3'' for Class 1 modems.
If the parameter begins with a ``!'', then the remainder of the
string is taken to be the identification string and no command
is issued to the modem.

ModemModelQueryCmd

The command to send to the modem to get the model identification string.
If this parameter is not set, then it is initialized to
to ``AT+FMDL?'' for Class 2 modems, or
to ``AT+FMM?'' for Class 2.0 modems, or
to ``ATI0'' for Class 1 modems.
If the parameter begins with a ``!'', then the remainder of the
string is taken to be the identification string and no command
is issued to the modem.

ModemNoAutoAnswerCmd

The command to stop the modem from automatically
answering when the phone rings.

ModemNoFlowCmd

The command to disable flow control between
DTE
and
DCE.

ModemOnHookCmd

The command to place the phone ``on hook''
(i.e. hangup).

ModemPageDoneTimeout

The maximum time to wait, in milliseconds, for a response
from the modem after sending a page of facsimile data (e.g.
the time to wait for a response to a Class 2/2.0
AT+FET
command).

ModemPageStartTimeout

The maximum time to wait, in milliseconds, for an initial
response from the modem when sending a page of facsimile data
(e.g. the time to wait for a response to a Class 2/2.0
AT+FDR
command).

ModemRate

The baud rate to use for DCE-DTE communication.
This value may be one of: 115200, 76800, 57600, 38400, 19200, 9600, 4800,
2400, 1200.
The default value is 19200 because many modems lock the
rate at 19200 when sending or receiving facsimile.
Note that not all values are supported by all operating
systems and modems; consult
stty(1)
for the available rates on your system.

ModemReadyCmds

A string of commands to issue to the modem during reception initialization.
This string is sent to the modem
after
the standard set of configuration commands required by the fax server.  This
is done, for example, to un-busy a DID line so that calls can come through.

ModemRecvFillOrder

The bit order to expect for received facsimile data.
This value may be either
LSB2MSB
when bits are ordered from least-significant-bit to
most-significant-bit (as in the
CCITT
specification) or
MSB2LSB
when bits are ordered in the reverse direction.
According to the various specifications all modems should return
data in
LSB2MSB
order.
However most Class 2 modems (except maybe only Multitech) use
MSB2LSB
for compatibility with modems that were built with
Rockwell hardware/firmware that included a bug
that was too widespread to correct.
If this parameter is not set, then it is autodetected and set to
LSB2MSB
for Class 1 and Class 2.0 modems and
MSB2LSB
for non-Multitech Class 2 modems. However this may be wrong for
your modem, so you will have to specify this parameter explicitly.

ModemRecvSuccessCmd

A string of commands to issue to the modem after a successful
receive session before the call is disconnected.

ModemResetCmds

A string of commands to issue to the modem during initialization.
This string is sent to the modem
before
the standard set of configuration commands required by the fax server.
Note that these commands should not include normal
reset commands that are specified through other parameters.
For example, commands to setup flow control,
DCD
handling,
DTR
handling, etc. should be specified through the appropriate
configuration parameters and not through this parameter.
In addition the soft reset command (usually ``ATZ'')
should not be included in this string; the servers issue this
command explicitly.

ModemResetDelay

The time, in milliseconds, to pause after setting
DTR
ON, while resetting a modem.
DTR
ON does not respond with ``OK'', so this parameter should
be long enough to allow the modem time to be ready for
ModemSoftResetCmd successively.

ModemResultCodesCmd

The command to enable result codes.

ModemRevQueryCmd

The command to send to the modem to get a firmware revision identification
string.
If this parameter is not set, then it is initialized to
``AT+FREV?'' for Class 2 modems, or
to ``AT+FMR?'' for Class 2.0 modems.
If the parameter begins with a ``!'', then the remainder of the
string is taken to be the identification string and no command
is issued to the modem.

ModemSendBeginCmd

The command to send to the modem upon establishing carrier during
a transmit operation.
This parameter is useful for systems that are incapable of enabling
hardware flow control without
DCD
asserted.

ModemSendFillOrder

The bit order the modem expects for transmitted facsimile data.
This value may be either
LSB2MSB
or
MSB2LSB
(see also
ModemRecvFillOrder above.)
Virtually all modems expect transmitted facsimile data in
LSB2MSB
bit order.

ModemSetVolumeCmd

The commands to use to set the modem speaker volume levels.
There should be five whitespace-separated commands,
one each for setting the
volume to ``Off'', ``Quiet'', ``Low'', ``Medium'', and ``High'';
the default is ``"ATM0 ATL0M1 ATL1M1 ATL2M1 ATL3M1"''.
See also
SpeakerVolume .

ModemSetupAACmd

The command to setup
"adaptive answer"
support in the modem-if available.
Adaptive answer is the term used for the ability to
distinguish between calls from facsimile, voice, and
data sources.
Note that this string is the last command issued by the device
drivers during setup, so the command string
may, if necessary, switch to a different
operating mode (e.g. on some Rockwell-based modems it is necessary
to issue the ``AT+FAA=1'' command in Class 0).

ModemSetupDCDCmd

The command to setup
DCD
handling.
On most systems the facsimile server will enable
the CLOCAL flag on the tty device to which
the modem is connected.
This should insure that the system does not close an open
file descriptor associated with the modem if carrier is dropped.
Thus, for most systems and modems
ModemSetupDCDCmd should setup
DCD
to reflect carrier.

ModemSetupDTRCmd

The command to setup
DTR
handling so that the modem is reset when the
DTR
signal is lowered by the host.
The facsimile server uses this facility to insure that modems
are not left in a ``locked up'' state.

ModemSoftFlowCmd

The command to setup software (XON/XOFF)
flow control between
DTE
and
DCE.

ModemSoftResetCmd

The command to force a soft reset of the modem.

ModemSoftResetCmdDelay

The time, in milliseconds, to pause after receiving the OK following
ModemSoftResetCmd before any further commands are sent to the modem.

ModemSoftRTFCC

Whether or not to enable software-driven Real-Time Fax Compression Conversion.
RTFCC allows HylaFAX to convert the image compression between MH MR and MMR
formats regardless of how faxq formatted the image file.
Note that when using RTFCC, the
compression format of the file will be ignored, thus the ``-1'', ``-2'',
and ``-3'' options for sendfax, ps2fax, and others will only influence how the
document is prepared by faxq and will not influence the
actual negotiated session parameters.
Class2RTFCC takes precedence over
ModemSoftRTFCC and if both are enabled, then software-driven RTFCC will not be performed
in favor of the firmware-driven RTFCC.

ModemType

This parameter must be set to one of: ``Class2'', ``Class2.0'',
or ``Class1'';
to indicate that the modem is a Class 2-,
Class 2.0-, or Class 1-style modem, respectively.
If this parameter is not set, then it is autodetected and
the highest supported fax class is used.

ModemVerboseResultsCmd

The command to enable verbose, as opposed to numeric, result codes.

ModemWaitForConnect

If enabled, the facsimile server will not consider a connection
established when answering an incoming call until a
``CONNECT'' status string is received.
This is useful mainly for Rockwell RC32ACL-based
modems that send ``FAX'' and ``DATA'' status
messages before sending ``CONNECT''.

ModemWaitTimeCmd

The command to set the
number of seconds to wait for a carrier signal
when placing a call or answering the phone.

FaxT1Timer

The value of the
T1
timer in milliseconds.
This timer is used to time out the initial session contact;
i.e. receipt of DIS/DCS.

FaxT2Timer

The value of the
T2
timer in milliseconds.
This timer is used to time out receiving responses and commands.

FaxT4Timer

The value of the
T4
timer in milliseconds.
This timer is used to time out the reception of
HDLC
frames and, usually, trigger frame retransmissions.

Class1Cmd

The command to set the modem into Class 1 operation.

Class1EnableV34Cmd

The command to enable V.34-fax support with at least the desired
maximum primary channel rate.

Class1ECMSupport

Whether or not to support T.30-A error correction protocol.  Use of
ECM will require 64 kilobytes of free memory per modem in active use.

Class1PersistentECM

Whether or not to continue to retransmit and allow to continue to
receive image data in ECM protocol
which is not accepted as valid after four successive attempts.

Class1ECMFrameSize

The size in bytes of image frames to transmit during ECM protocol.
This setting will also indicate a preference in receive sessions.
The only acceptable values are 64 and 256.  A setting of 64 may
be useful on high-load systems and possibly environments with
extremely poor line quality.

Class1ExtendedRes

Whether or not to support resolutions other than normal and fine.
This option has been deprecated by
Class1Resolutions.

Class1FrameOverhead

The number of extraneous bytes in
HDLC
frames sent to the host in response to an ``AT+FRH'' command.
For modems that properly implement the Class 1 interface, this
number should be 4 (the default).

Class1HFLOCmd

The command to setup hardware (RTS/CTS)
flow control between
DTE
and
DCE
when operating in Class 1.
This command is issued immediately after sending the
Class1Cmd to switch the modem to Class 1 operation.

Class1NFLOCmd

The command to setup no flow control between
DTE
and
DCE
when operating in Class 1.
This command is issued immediately after sending the
Class1Cmd to switch the modem to Class 1 operation.

Class1PPMWaitCmd

The command used to stop and wait before sending the post page message,
except before sending EOP, when
Class1EOPWaitCmd is used instead.  We must ensure that the high-speed carrier has
stopped completely.
According to T.30, Chapter 5, Note 4, this delay should be 75 +/- 20 ms.

Class1ResponseWaitCmd

The command used to stop and wait after sending TCF, before attempting to
receive a training response from the remote.  Set this to ``AT+FRS=1'' if
you experience ``DIS/DTC received 3 times'' errors.

Class1Resolutions

A bitmapped (bit-or'd) value indicating the resolutions to be supported during facsimile
operation.  Individual resolutions follow Table 21/T.32 and are defined as follows:

Bit	Description
0 (0x00)	R8 x 3.85 l/mm, Normal
1 (0x01)	R8 x 7.7 l/mm, Fine
2 (0x02)	R8 x 15.4 l/mm, Superfine
4 (0x04)	R16 x 15.4 l/mm, Hyperfine
8 (0x08)	200 dpi x 100 l/inch
16 (0x10)	200 dpi x 200 l/inch
32 (0x20)	200 dpi x 400 l/inch
64 (0x40)	300 dpi x 300 l/inch
 .5

Thus, a value of 3 would indicate support for normal, fine, and superfine resolutions.

Class1RMQueryCmd

The command to send to the modem to get the list of supported reception bit-rates. If the parameter begins with a ``!'', then the remainder of the string is taken to be the modem response and no command is issued to the modem.

Class1TCFWaitCmd

The command used to stop and wait before sending TCF, similar to Class1PPMWaitCmd. According to T.30, Chapter 5, Note 3, this delay should be 75 +/- 20 ms.

Class1TMQueryCmd

The command to send to the modem to get the list of supported transmission bit-rates. If the parameter begins with a ``!'', then the remainder of the string is taken to be the modem response and no command is issued to the modem.

Class1EOPWaitCmd

The command used to stop and wait before sending the post page message similar to Class1PPMWaitCmd. We allow a different setting in the case of EOP, however, because empirically some machines may need more time.

Class1MsgRecvHackCmd

If receive failures occur due to +FCERROR just prior to image data reception, setting Class1MsgRecvHackCmd to AT+FRS=1 may help.

Class1RecvAbortOK

The time, in milliseconds, to wait for an ``OK'' result code from the modem after aborting an HDLC frame receive (``AT+FRH=3''). If this number is zero, then the modem is assumed to not correctly implement aborting and instead the driver will wait 200ms, flush any input, and then send ``AT\n'' and wait 100ms for an ``OK'' result.

Class1RecvIdentTimer

The time, in milliseconds, to wait for an initial DCS when receiving a facsimile. CCITT recommendation T.30 specifies this as the value of the T1 timer. However, adaptive answering schemes such as that described above under the AdaptiveAnswer parameter may require that this timer be shortened.

Class1SendMsgDelay

The time, in milliseconds, to delay just before sending the image data. According to T.30: 5.3.2.4 this should be no less than 75 ms; however, in practice some receivers are slow to drop their CFR transmission carrier and need more time to start up their reception carrier.

Class1SwitchingCmd

The command used to ensure that the sending facsimile device has turned off its modulator (i.e. loss-of-carrier) as recommended by T.31: Appendix II.1.

Class1SFLOCmd

The command to setup software (XON/XOFF) flow control between DTE and DCE when operating in Class 1. This command is issued immediately after sending the Class1Cmd to switch the modem to Class 1 operation.

Class1TCFMaxNonZero

The maximum percentage of non-zero data bytes permitted in an acceptable received TCF. Note that this number does not include any leading non-zero data in the received data. See also Class1TCFMinRun .

Class1TCFMinRun

The duration, in milliseconds, of the minimum run of zero data in an acceptable received TCF. This value should be specified according to a 1.5 second transmission of zero data (i.e. it should be between 0 and 1500). See also Class1TCFMaxNonZero .

Class1TCFRecvHack

Deliberately look for the low-speed carrier loss before switching to the high-speed TCF carrier.  Use this if session logs consistently show +FCERROR prior to TCF reception.

Class1TCFRecvTimeout

The maximum time to wait, in milliseconds, for the first byte of the Training Check (c TCFc ) message data that is received during the training phase of the facsimile reception protocol.

Class1TCFResponseDelay

The time, in milliseconds, to delay between receiving TCF and sending a response on the v.21 carrier to indicate whether or not training was successful.

Class1TMConnectDelay

The time, in milliseconds, to delay after receiving CONNECT following +FTM before sending image data.  T.31 8.3.3 requires the modem to respond with CONNECT before the modulation training pattern.  If transmission begins before the remote has successfully completed its own modulation training pattern then data, especially during TCF, could be lost.  Many modems do not follow T.31 in this regard, and thus the default is zero; however its use with such modems would likely have a negligible effect.

Class1TrainingRecovery

The time, in milliseconds, to delay after a failed training session. This time is used when sending training and when waiting for DCS and subsequent training during receive.

Class1ValidateV21Frames

Whether or not to use the FCS bits of received V.21 HDLC frames to check the validity of the frame itself.  Most Class 1 modems perform this check independently (per T.31 7.4) and do not require this feature to be enabled.

Class2Cmd

The command to set the modem into Class 2/2.0 operation.

Class2AbortCmd

The command to use to abort an established session. After using this command to abort a session, the fax software will send ModemOnHookCmd and then reset the modem by dropping DTR .

Class2APCmd

A largely unused option for modems supporting ITU-T.32, Class 2.1, standards.  This command would be used to enable sending and receiving SUB, SEP, and PWD frames.

Class2APQueryCmd

A largely unused option for modems supporting ITU-T.32, Class 2.1, standards.  This command would be used to query the capabilities of sending and receiving SUB, SEP, and PWD frames. The value ``none'' may be used if the modem does not support any Class2APQueryCmd.

Class2BORCmd

The command to setup the bit order of sent and received facsimile data. Usually the command ``AT+FBOR=0'' is used so that data is sent and received in direct bit order (LSB2MSB). Some modems, such as the Everex 24/96D, must use reversed bit order for Phase B and D data exchanges to avoid a bug that results in garbage data being placed in the padding of EOL codes. The bit order specified by this command must correspond to the settings of the ModemSendFillOrder and ModemRecvFillOrder parameters.

Class2BUGCmd

The command to use to enable or disable the tracing of HDLC frames sent and received by the modem. This tracing information should be returned to the host in ``+FHR:'' and ``+FHT:'' status strings. Note that many Class 2 modems do not support this facility, which is largely used for diagnostic purposes. The value ``none'' may be used if the modem does not support any Class2BUGCmd.

Class2CIGCmd

The command used to set a polling identifier. This string is inserted into the format ``%s="<id>"''.

Class2CQCmd

The command to use to set up parameters for copy quality checking. For example, for an Everex 24/96D modem this parameter might be set to ``AT+FCQ=1\nAT+FBADMUL=20\nAT+FBADLIN=10''. Class2CQCmd should be configured to set-up all available copy quality services available per Class2CQQueryCmd. To disable features that are available, configure Class2CQQueryCmd with a ``!'', and then set Class2CQCmd accordingly.

Class2CQQueryCmd

The command to send to the modem to get the copy quality capabilities string. If the parameter begins with a ``!'', then the remainder of the string is taken to be the capabilities string and no command is issued to the modem; this can be used together with the Class2CQCmd to force copy quality checking to be done in the server instead of in the modem. See also PercentGoodLines and MaxConsecutiveBadLines for parameters used to do server copy quality checking.  If copy quality checking is configured to be done by the modem then it is not done by the server.

Class2CRCmd

The command to use to enable the reception of facsimile.

Class2DCCCmd

The command used to set modem capabilities. This string is inserted into the format ``%s=vr,br,wd,ln,df,ec,bf,st''.

Class2DCCQueryCmd

The command to send to the modem to get the Class 2/2.0 capabilities. If the parameter begins with a ``!'', then the remainder of the string is taken to be the capabilities string and no command is issued to the modem.

Class2DDISCmd

The command to set session parameters before dialing. This string is inserted into the format ``%s=vr,br,wd,ln,df,ec,bf,st''. Setting this parameter enables support for Class 2 modems that do not properly implement the ``AT+FDIS'' command by setting up session parameters before dialing the telephone.

Class2DISCmd

The command used to set the current session parameters. This string is inserted into the format ``%s=vr,br,wd,ln,df,ec,bf,st''.

Class2ECMType

The interpretation of the EC parameter in the modem DCC response varies between the Class 2, ``2'', and Class 2.0, ``2.0'', specifications.  This configuration parameter allows the administrator to specify which type to use.  The corresponding specification type is used by default.

Class2HexNSF

Whether or not to parse the NSF strings reported by the modem using hexadecimal values.  By default, they are parsed as hexadecimal values.

Class2HFLOCmd

The command to setup hardware (RTS/CTS) flow control between DTE and DCE when operating in Class 2/2.0. This command is issued immediately after sending the Class2Cmd to switch the modem to Class 2/2.0 operation. For Class 2.0 operation the default is ``AT+FLO=2''.

Class2LIDCmd

The command used to set the local identifier string. This string is inserted into the format ``%s="<id>"''

Class2MINSPCmd

The command used to set the minimum acceptable speed to be negotiated for transmitting page data. This string is inserted into the format ``%s=<speed>''

Class2NFLOCmd

The command to setup no flow control between DTE and DCE when operating in Class 2/2.0. This command is issued immediately after sending the Class2Cmd to switch the modem to Class 2 operation. For Class 2.0 operation the default is ``AT+FLO=0''.

Class2NRCmd

(Class 2.0 only) The command to setup negotiation message reporting. For the correct operation of the Class 2.0 driver this command must enable the reporting of: receiver parameters, transmitter parameters, and ID strings. It is not necessary to enable reporting of non-standard frames for correct operation of the Class 2.0 driver.

Class2PACmd

A largely unused option for modems supporting ITU-T.32, Class 2.1, standards.  This command would be used to set up the polling address string enabled by the Class2APCmd .

Class2PHCTOCmd

The command to use to set the Phase C timeout parameter (in seconds). The value ``none'' may be used if the modem does not support any Class2PHCTOCmd.

Class2PIECmd

(Class 2.0 only) The command to use to control procedure interrupt handling. Procedure interrupts should be disabled because (Fx does not provide a mechanism for dispatching procedure interrupts to an administrator.

Class2PTSCmd

The command to use to set the received page status code. When copy quality checking is done in the host, this command may be used to control the post-page response delivered to the sender. Beware that some modems do not properly implement this command in which case the server should be configured to not do copy quality check: see the PercentGoodLines and MaxConsecutiveBadLines parameters to understand how to defeat copy quality checking.

Class2PTSQueryCmd

The command to use to query the received page status code. This command may be used to determine the post-page response returned from the receiver. Beware that some modems do not properly implement this command in which case this setting should be set to ``none''.

Class2PWCmd

A largely unused option for modems supporting ITU-T.32, Class 2.1, standards.  This command would be used to set up the password string enabled by the Class2APCmd .

Class2RecvDataTrigger

The character to send to the modem to trigger the transmission of received data from the modem to the host. This character is specified to be DC1 (octal 21) in the draft specification 2388-A and DC2 (octal 22) in the 2388-B specification. Most Class 2 modems accept DC1 or both DC1 and DC2. Some modems however only accept DC2. Note that string parameters may use C-style escape sequences, so DC2, for example, would be specified as ``"\022"''.

Class2RELCmd

The command to use to enable the delivery of byte-aligned EOL codes in received facsimile. If this parameter is defined, then received facsimile data will be marked to indicate that EOL codes are byte-aligned; otherwise they will be marked as not (necessarily) having byte-aligned codes.

Class2RTFCC

Whether or not to enable MultiTech's Real-Time Fax Compression Conversion which is available in later firmware revisions for the MT5634ZBA-V92, MT5634ZPX-PCI-V92, and other models.  RTFCC allows HylaFAX to convert the image compression between MH MR and MMR formats regardless of how faxq formatted the image file.  If RTFCC is available with your firmware, then the response to ``AT+FFC=?'' is non-zero.  Note that when using RTFCC, the compression format of the file will be ignored, thus the ``-1'', ``-2'', and ``-3'' options for sendfax, ps2fax, and others will not influence the actual negotiated session parameters.

Class2SACmd

A largely unused option for modems supporting ITU-T.32, Class 2.1, standards.  This command would be used to set up the destination subaddress string enabled by the Class2APCmd .

Class2SendRTC

Whether or not to append an explicit ``Return To Control'' (RTC) signal to the page data when transmitting. The Class 2 and Class 2.0 specs (i.e. SP-2388-A and TIA/EIA-592) state that the modem will append RTC when it receives the post-page message command from the host; this parameter is provided in case the modem does not correctly implement this.

Class2SFLOCmd

The command to setup software (XON/XOFF) flow control between DTE and DCE when operating in Class 2/2.0. This command is issued immediately after sending the Class2Cmd to switch the modem to Class 2/2.0 operation. For Class 2.0 operation the default is ``AT+FLO=1''.

Class2SPLCmd

The command to use to enable a polling request. The value ``none'' may be used if the modem does not support any Class2SPLCmd.

Class2TBCCmd

The command to use to enable stream-mode communication between the host and modem. The value ``none'' may be used if the modem does not support any Class2TBCCmd.

Class2UseLineCount

Whether or not to use the line count reported to HylaFAX by the modem firmware decoder.

Class2UseHex

Whether or not to parse the capabilities strings reported by the modem using hexadecimal values.  By default, they are parsed as decimal values.

Class2XmitWaitForXON

Whether or not to wait for an XON character from the modem before sending facsimile data to the modem for transmission. Note that this is only relevant for modems that conform to the Class 2 spec (i.e. SP-2388-A). The Class 2.0 specification states that the host may transmit data immediately upon receiving CONNECT and that no XON character will be sent to the host.

PagerSetupCmds

The commands to send to a modem to prepare the modem for a call to pager service provider. Typically these commands place direct the modem to communicate with the service provider at 300 bps using the V.21 protocol. Per-service provider command strings can be setup in the info database; see hylafax-info (5).

PagerMaxMsgLength

The maximum length for a pager text message. Messages longer than this number are truncated. Per-service provider message lengths can be setup in the info database; see hylafax-info (5).

IXOService

(IXO/TAP only) The service identification string transmitted as part of the IXO/TAP protocol.

IXODeviceID

(IXO/TAP only) The terminal device identification string transmitted as part of the IXO/TAP protocol.

IXOMaxUnknown

The maximum number of unrecognized messages that will be accepted at various stages of the IXO/TAP protocol before the sender will abort and hangup the phone.

IXOIDProbe

(IXO/TAP only) The time, in seconds, between sending a ``\r'' during the initial ID recognition sequence of the IXO/TAP protocol.

IXOIDTimeout

(IXO/TAP only) The maximum time, in seconds, to wait for the initial ID response from the service provider.

(IXO/TAP only) The maximum number of attempts to login to a service provider.

IXOLoginTimeout

(IXO/TAP only) The maximum time, in seconds, to wait to complete the login procedure.

IXOGATimeout

(IXO/TAP only) The maximum time, in seconds, to wait for a Go-Ahead message from the service provider.

IXOXmitRetries

The maximum number of times to try sending a text message block in a single call.

IXOXmitTimeout

The maximum time, in seconds, to try transmitting a text message block.

IXOAckTimeout

(IXO/TAP only) integer 30 IXO: max time to wait for msg block ack (secs) The maximum time, in seconds, to wait for an acknowledgement to a transmitted message.
