  As far as your concurrency question about async ports goes...

   The communication libraries supplied with LogiTech are quite good.  The
async routine is run off the IOTRANSFER command.  So it will interrupt your
main process as a character is received (but only for a brief moment).  All the
characters are stored in a 1K buffer (but it can be expanded if you have the
sources).

   If you want, I can send you an example of a terminal program written with
the LogiTech libraries.
