If you want to use the comm ports on an interrupt
driven basis, get the Async Comm Support software from
IBM. It has a routine (RS232INT.EXE or RS232INT.BAS)
which run the port on an interrupt driven basis, and
with a little work, can be interfaced with any C. I
have an interface with PASCAL. The only trick is to get
Version 1.0 of the program since it details what the
entry points do. If you can not, I will be glad to help
you with it. I recommend it since it will run and
interface the PC to UNIX(tm) at speeds upto 9600
without dropping characters, which is the standard
complaint that I have been hearing with people who are
trying to interface with it a character at a time.
