Jim:

We use polled and interrupt driven serial i/o routines that are written
in C and go directly to the hardware; these work fine in dos and (in a
dos box) in Win3.11 and Win95. Win-NT is a different beast, but if my
experience with real operating systems (which NT is getting to be one
of) is any predictor, the problems should be lessened, not made worse.
Our routines are compatible with various flavors of Unix once the C code
is translated. Dealing with the serial hardware is pretty straight
forward and pretty universal at that level, including the use of
interrupts. We haven't found any hardware our stuff doesn't work on yet.

You should be able to get exactly the same results by just following
your nose. (The NT stuff will require a different approach.)
