Nrports is an ASCII file that contains information about each of the NET/ROM
ports that are to be used. When dealing with an NET/ROM utility such as
call, it takes an optional argument that is the port name. This port name is a
reference to the line within
nrports, which has the same name. The information on each line contains
enough information to bind the command to a particular NET/ROM
interface, this binding is done by matching the callsign on the line in
nrports with the callsign of the port set by
ifconfig. The
nrports file may contain comments that begin with a # in the first column, or a port
description in the following format, each field being delimited by white space:
name callsign alias paclen description
The field descriptions are:
name
this is the unique NET/ROM port identifier.
callsign
the callsign of the NET/ROM interface to bind to.
alias
this is the alias of the NET/ROM port.
paclen
is the default packet size for this interface.
description
a free format description of this interface, this field extends to the end
of the line. It may contain spaces.
