Roland,

Before we can get started people need to know the following:-
1) What comms library?
2) What version?
3) Have you read the docs that come with the comms library?
4) Is there an example that comes with the comms library?

After answering these then I may be able to help. 

Some other items you need to check out WRT (with reagrds to) which
comms library you should use:-
1) What is the larghest number COM port you need to use?\
2) Do you need to use multiple comm ports at once?
3) Do yuo need 9 bit / wake-up mode support?
4) Do you need to use high speed  comms? (Use 1655x buffer?)
5) Need to also use a timer? Check for RX packet within a certain
time?
6) Ability to use Allegro at the same time?
7) Ability to easily extend the code?
8) Are there any C++ wrappers available? (None have this as far as I
have seen. May be 100% wrong, If I am please send me an email ASAP)
9) Comms library support a large TX & RX buffer for interrupt
tansmission / receiving?

Once you have looked at these issues then you will be in better shape
to pick the correct DJGPP comms library. If you do not know how to
answe these questions then please lee me know what you need the ASYNC
library for? If you just need a data logger then check out my home
page at http://homepages.ihug.com.au/~acottrel/ where you can download
the full source for DSCOPE, no warranty is given for this. It has some
save /load bugs, but I haven't seen then yet.
