For 1200 and 2400 baud connections, set register 50 to '0', not
the documented '2' or '3'. I have found that a setting of 2 or 3
makes the TB *very* picky about what it sees on the remote end.
Connections that always fail will start working with a setting of
0. There may be situations where you need to force a 1200 baud
connect with S50=2, but I have yet to run across one.

No, just lock the interface speed down to 19200 and let the modem
do the work.--
