Telnet locking up.....

[Robert Dal Santo]

BACKGROUND

	A Sun 3/260 running SunOS 3.5 standard from the tape. No
patches installed.

	A MicroVax II running the latest version of More BSD from Mt. Xinu.

PROBLEM

	I can telnet from my Sun to other Sun's running 3.5 and 4.0.1 with
no problems. I can telnet to other MicroVax's running an older version of
MoreBSD. However, when I telnet to the MicroVaxs with the latest version
of More BSD I have problems. The local outgoing telnet goes into an infinite
loop when I hit the interrupt key. This only happens when talking to the
MicroVaxs running the latest More BSD. Ethernet terminal servrers that use 
telnet still talk fine to the MicroVaxs. When the telnet goes into the loop
it can be exited using the Control-] to get to command mode, but the interactive
session on the remote machine never comes back.

	dbx'ing the running code to try to see where it is indicates it is
leaping around all over the place, but definately in an infinite loop.

	Can anyone offer suggestions to a possible cause/solution before I
start some long code tracing in an attempt to work out what is happening??
Has this happened to anyone else ? The same problem occurs if I use a version
of telnet from the (4.3?) BSD networking release.

Thanx,
