Serial communication

[Sarah Reichelt]

Hi Bill,

I have sucessfully sent & received through a serial port, only with Mac OS
9.1 but I don't see why it wouldn't work with OS X.

The Keyspan adapter allows it's port 1 to be referred to as "printer:" so
that should work without any problem.

You need to set the serialControlString to show the parameters for your
communications e.g. "BAUD=9600 PARITY=N" etc etc, rather than setting it to
the name of your port. Or don't set it at all to use the defaults, but
that's probably a bad idea.

I have a test communications stack that I can make available or send to
anyone that is interested.

Cheers,
Sarah
