/BEEP_TERMINAL = "hot-key-defintion"

   Defines a hot-key sequence which when pressed will cause both the
   watcher's and watchee's terminals to ring their bells. This may be
   used to get the other user's attention while watching him.

   The default value is defined in the logical WATCHER$BEEP_TERMINAL.

   With PEEK, the user being watched can also beep both terminals if he
   has input control. With SPY, only the watcher can beep both terminals.

   Example:

         $ PEEK/BEEP_TERMINAL="<F6>" USER1
      or
         $ DEFINE WATCHER$BEEP_TERMINAL "<F6>"
         $ PEEK USER1

   In either case, pressing the F6 function key will cause the bell to
   be rung on both terminals.
