killing a login on Zilog

[cnrdean at topaz.berkeley.edu]

Every once in a while, a "login" process runs forever on our Zilog
8000/31 computer.  I cannot kill this process, and nobody can use
that port.

The only solution is to reboot the whole system, which is a drag.

I know the cause of the problem (ie. what causes the login to get
stuck).  But, assuming that I can't make that go away, I need to
find out how to kill this process.

Any ideas?

Thanks.
