Ever done "strings /unix" on your SCO pc? (After ln /xenix /unix)
There's a message: "Port Shutdown Follows Catastrophy." 
Has anyone else seen this?  We are getting this and it causes
our whole computer to lock up; none of the console screens will
even accept any input.  What can cause this?  Of course we are
introducing random bursts of square wave through a coupler on
one of the ports, but we expect this is operational mode.
We know the doctor says: "If it hurts when you do that, why do
you do it?"
