Thx for replying.
This application is a text MODE application.  It is a DOS text mode app.
The runtime is very portable. Dataflex does run on DOS, OS/2, Unixes and
Windows (3.1, NT, 95).  The runtime is written to be portable. As a result
they implemented the lowest common denominator.  The way we worked around
the COMM port issues in a DOS environment is use a 3rd party TSR to accept
input from the COMM ports and re-direct it into the keyboard buffer.  In
our application it seems like the operator have typed it in.
Thx.
