Done, Peter but not tested as motor power is hand controlled on that
machine. As it is on the other 2, only the pi can power things up via an
ssh login.
BUT this might show what J. Ray Mitchel is encountering with his
non-functioning F9-F10 buttons. Captured from the terminal screen LCNC
was launched from. This should have activated my fwd/rev leds in the gui
even if the tach stayed at zero, it did not activate the direction
tallies:

Thanks Peter. Is there a new man page? I think I may be looking at the
old one.
