Just put on OUTPUT the caracter w/ ASCII code is 80h.

                Mscomm.output=asc(128)
                (128d=80h)

If you work using text in the input mode, your work will be quite easy than work
with binary. But I believe that
ocurrs a problem if you must work w/ ASCII 00h, since this one is the null
caracter(and doesn't have string
representation). To send 80h works fine.
