          ...And a few that *are* reserved by VMS.  See below.

          Yes.

          The VMS terminal driver uses ^U as an 'Un-type this line'
          key -- it deletes to the beginning of the line.

          ^X is a little more subtle:  DEC uses ^X for the 'clear
          *all* pending input' key.  If there is input in the
          type-ahead buffer, it is cleared.  If there is nothing in
          the type-ahead buffer, then the terminal driver treats ^X as
          if it were ^U.

          As a matter of fact, when you press ^X, TPU will not see it.
          The terminal driver will pass a ^U to TPU.  For proof, use
          the EVE command SHOW KEY, and press ^X.  You will be told
          that "CTRL/U is defined as blah blah blah".

          All of this is on the assumption that you have a
          more-or-less normal terminal setup.  I suspect that if you
          are running in PASTHRU or PASSALL mode (don't attempt this
          at home :-), the ^X will be passed as is.

          I hope this helps....
