801/212s

I wasn't sure where this was supposed to go...
I have problems with my Bell 801/212s.

The 212s sometimes finish their conversations and the TR light stays
on.  This seems to keep it from establishing new consversations.
Pushing AL and ST don't turn TR off.  If I try to open the TTY line
associated with the 212, the open just sits there and doesn't return.
I am running 4.1bsd on a 780 with dz's; they are configured to NOT hang
up on last close, but cu and uucp do ioctl to set hang up on close.

This problem seem to appear and disappear randomly.
Sometimes the lights end up in other odd states.

If my 212's and 801's are in strange states, is there anything I can do
(with software preferably, or else with the switches) to init my acu
lines?  Does anyone else have this experience?
