Why do you want to write a program yourself? There are some simple fax
solution you can send a .txt file to a fax from commandline. (i.e. quicklink
fax)

I've only three (very) old documentations about T4 and the AT commands for
fax. But they where enough to write the program.

I've stored the files on my web server:
http://www.wedo.at/ccitt_t4.txt and
http://www.wedo.at/class2.txt and
http://www.wedo.at/class2.htm .

Hope this will help you, too.

cu, Doc ...
