Thanks to all who responded with ideas and patches for using a Trailblazer
Plus with UUCP on a Sun 3/160.
Most of my problems stemmed from strangeness in our version of UUCP (based
on some old RTI-4.3 style code). I traced our dialing problems to the
manner in which the Trailblazer behaves after seeing an "AT DT" sequence,
but before the other end picks up.
I solved this one by writing my own dialer for a Trailblazer, based on the
hayestone dialer. I added some more informative error logging and made it
a little more tolerant of the TB "RRING" verbose return code.
The result is that we're online at 19200, and I ported the code rather
quickly to a Silicon Graphics 4D/80GT, which had even larger headaches
dealing with high speed modems.
