Hmmm, that sounds like possibly a buffer overflow in the 
terminal. Some terminals had really slow micros running 
them, and needed to stop transmission from the host for a 
while.  If the host is not obeying the stop-sending command 
(could be the terminal is using the CTS line that is not 
wired to the VAX, or the VAX is not set to obey Xoff/Xon 
characters) then this would happen.
