computer opeating systems. Unix based systems terminate each line with
a
single <new-line> character. MSDOS and some other systems use a
combination <carriage-return, new-line> pair of characters to terminate
a
line. Stated another way, in MSDOS, the <carriage-return> simple
returns
the cursor to the beginning of the current line while <new-line>
advances
the cursor one line with character position the same distance from the
beginning of the line. In Unix systems, the <new-line> infers a
carriage
return.
How your system responds is defined in the 'struct termios' associated
with
the current terminal be it a video console, a printer or a serial port.
The specific flags you want to change are 'OPOST | ONLCR'. I lost the
thought stream in your question but I suspect that you need to add these
flags to the '/etc/gettydefs' of PC A. The counter part is 'IGNCR'.
Refer to manual pages 'stty(1)' and 'termios(7)'. I have prepared a
blurb
concering the 'struct termios'. If you would like a copy, I can e-mail
a
copy.
