Ugh, this topic rears it's ugly head again.  I, too, am still living
with the problem, knowing full well what it is and how to fix it.  No
one at Illinoisy Bell really gives a rats arss about my problem.

It is a CO synchronization problem.  Over a T1 digital trunk, if the
offices are not sync'ed, a "digital slip" occurs periodically which is
the result of one end re-synchronizing.  This causes a PSK error that
hoses one direction of the 1200 baud signal.  Fortunately for me (??)
that error is only "seen" by my terminal, and not the host.  Really screws
up vi and other terminfo-based programs.
