[comp.sys.mac.hypercard] Serial XCMDS for HC 2.0

patnaik@SNUFFLEUPAGUS.NRL.NAVY.MIL (Gopal Patnaik) (03/20/91)

I have been using XCMDS to write to the serial port under HC 1.2.5.  However
these fail to work reliably with HC 2.0v2 (with system 6.0.5 or 6.0.7). I
also need to send the NULL byte; I did this by suitably modifying the source
to the serial XCMDS.  Does any body have serial XCMDS that work under 2.0
and can send the NULL byte? Or does anybody have the sources to serial XCMDS
that work under 2.0 and I can make the changes myself.  I will be grateful for
any help.

Thanks.

ps. I am using HC for real-time control of model trains.
