As Jerry Leichter noted, the circuit timer has nothing to do with
timeouts and retransmission.  What you DO want to do if running
LAT thru a lot of bridges (as we do here) is to jack up the following
parameters to their maxima:

KEEPALIVE TIMER to 255 seconds
RETRANSMIT LIMIT to 120 seconds

These parameters should be changed on both the DECserver and host
sides.
