I have an application that writes a byte-at-a-time to the comm
port.  This works fine under DOS, but under OS/2 it requires an
OS call, which is not fine at all!!!  What is the simplest way
to overcome this problem, and please don't suggest that the
application itself be rewritten, as the goal is to make OS/2
provide the same facility as DOS, which is fast character comms.
I don't mind sticking some comms routines between the application
and the OS, but I'd like the simplest comms routines required.  I
can imagine that a multithreaded comms package would solve the
problem by filling a buffer until the thread is terminated, and
then send the next buffer.  BFN.  Paul.
