[HECnet] UPS driven OPC$CRASH?

There was a thing called "REMOTE-SHUTDOWN-LISTENER" which would wait for a connect to a particular TCP port and then run OPC$CRASH when that happened. It was intended for use with simh to allow the guest VMS OS to be shut down automatically when the host OS shuts down. Not exactly what is wanted, but it shouldn't be too hard to adapt to listen to a serial port instead. Don't remember who wrote it, but the C source is included. I put a copy in LEGATO::REMOTE-SHUTDOWN-LISTENER.ZIP. Bob
