Can you elaborate on that?

If the application calls txch(), how can I implement txch() so
that if there's a lot of data to transmit, it will bundle it up,
but if there's only a small amount of data, maybe just the one
byte, it will send it straight away?  I want to implement this
behaviour from the comms package side, not the application, as
the whole point is to be able to port DOS programs to OS/2
easily without requiring the user to rewrite their application.
Thanks + bye.  Paul.
