When I accidently hit two keys at the same time on my 1040ST, while
using the VT52 emulator desk accessory, the serial port sometimes locks up.
It will not send and most (but not all) of the time will not receive.  On
occasion, the host computer has continued to send data but my ST would not
send, but on almost all (I would estimate 95% of the time) occasions
both directions lock up.  The system otherwise functions normally.  The
only way to solve the problem is to reboot.
   I have never had this happen with any ST telecommunications program
other than the VT52 emulator, though I have on many occasions sat there
banging away on two keys to try and make it happen.
   It is a repeatable problem with the VT52, however.
   Does anyone know why this happens?  Has anyone else had this problem
or is there something wrong with my machine?  (unlikely, because all
other programs work fine.)  Is there a fix for this, like a new version
of the VT52?
  Thanks...
