They are written in C. I believe there must be comparable routines in the pascal dir. Or else, it won't be too difficult to translate the C routines into TP. You can email me for more information.

The "tasync" package mentioned above makes use of interrupt-driven output, it works on all other modems I have tested but not in ZOOM. Anybody else has the same problem? Or just the specific ZOOM I have tested is bogus? Bryan So
