Serial comm differences between PC & Mac?

Wow! Thanks for your efforts, Dar.

Your results are interesting, if not confusing. Do you think this is a bug
(& therefore should be entered in bugzilla)?

Fortunately, since the phone system only uses a certain set of chars, I
can filter out all of the junk, & make this work for my needs. BTW, I'm
using both the keyspan usa-28 & usa-28x on OSX, & com1 on the PC. The
results are the same with either keyspan adapter.
