There are several ways of defining the control codes for string capabilities:
Normal Characters except '^','\' and '%' repesent themself.
A '^x' means Control-x.  Control-A equals 1 decimal.
\x means a special code.  x can be one of the following charaters:
  E Escape (27)
 
 n Linefeed (10)

 r Carriage return (13)

 t Tabulation(9) 

 b Backspace(8) 

 f Form feed (12)

 0 Null character.  A \xxx specifies the octal character xxx.
  
     
  i 
 Increments paramters by one.
 
 
  r 
 Single parameter capability
 
 
  + 
 Add value of next character to this parameter and do binary output
 
 
  2 
 Do ASCII output of this parameter with a field with of 2
 
 
  d 
 Do ASCII output of this parameter with a field with of 3
 
 
  % 
 Print a '%'
If you use binary output, then you should avoid the null character
because it terminates the string.  You should reset tabulator expansion
if a tabulator can be the binary output of a parameter.
 
 
  Warning: 
 The above metacharacters for parameters may be wrong, they document Minix
termcap which may not be compatible with Linux termcap.
The block graphic characters can be specified by three string capabilities:
 
 
  as 
 start the alternative charset
 
 
  ae 
 end it
 
 
  ac 
 pairs of characters.  The first character is the name of the block graphic
symbol and the second characters is its definition.
The following names are available:


  

+	right arrow (>)
,	left arrow (<)
.	down arrow (v)
0	full square (#)
I	latern (#)
-	upper arrow (^)
'	rhombus (+)
a	chess board (:)
f	degree (')
g	plus-minus (#)
h	square (#)
j	right bottom corner (+)
k	right upper corner (+)
l	left upper corner (+)
m	left bottom corner (+)
n	cross (+)
o	upper horizontal line (-)
q	middle horizontal line (-)
s	bottom horizontal line (_)
t	left tee (+)
u	right tee (+)
v	bottom tee (+)
w	normal tee (+)
x	vertical line (|)
~	paragraph (???)



  The values in parentheses are suggested defaults which are used by curses,
if the capabilities are missing.
