Hey, all of you terminal hackers out there.  I finally found the way
to change brightness on an h19 terminal that does not have the knob.

First of all, you cannot do it in software.  You can turn on the key
click and many other things using the escape sequences, but not the
brightness.

I finally found how to do it.  It's really sick.  There is a potentiometer
for brightness and other controls UNDER THE HOOD (!!) on the video board.

The stupid thing is that when you open the hood, the first thing you
see is the message saying that you should't be opening the hood or you
will get zapped.  Then you see the video board and all the labeled components.

A nice terminal otherwise.
