You can begin by opening "COM1" or "COM2" as if it were a file, and
then using functions that read and write files, like `read', `write',
etc.

If this is somehow not good enough, the DJGPP FAQ list mentions in
section 22.3 several packages that can be used with DJGPP for
establishing serial communications.
