	There is good news and bad news. The good new is that the attached
    program was provided by someone at Interactive and it seems to work.
	The bad news is that after this program is run, switching to/from
    a VT running X can wedge the keyboard, rendering it useless for X.
    Sometimes switching back and forth can fix the X server, but
    when I reported this bug to Interactive, they recommended that I
    stop using this tool and I have not had the problem since.
	I've stopped using VT's now that I run X, so this is not too much
    of a problem for me.
