There are a number of comms libraries for DJGPP and they all work
under IWn 95,98,ME, NT 4.0, Win 2000 and XP. I have used the same
application on all of these Windows versions (with the exception that
to use it on WIN 2000 and XP I had to use the 2.04 LIBC as I use file
I/O).

Now for some things to consider:-
- Some also work with Linux. 
- Some support wakeup mode (aka 9 bit). 
- Some support only one com port and other support up to 16/32/64 (I
can't remember as I only used a maximum of 2 at a time.
- Some have a C++ wrapper available for them (never used the wrapper)
- Some are all in assembly
- Some need to be modified to use the latest GAS (GNU Assember)

To start with have a look in the V2TK directory and see what is in
there. I personally have used DZCOMM and PMCOM over the years. The
latest DZCOMM is available from sourceforge. I have a beta of PMCOM
1.1 if you decide to use PMCOM. 

I also have a data sniffer available with full source that I can send
you that I license under the GNU GPL license. It uses PMCOMM and bits
from ALEGRO for keyboard and timing. If you want this then let me know
and I will email it to you, its about 300K zipped from memory.
