[Lcdproc] Reading keys from MX400 series

[Eric H. Johnson]

Hi all,

I have likely overlooked something simple, but I do not see how to read the
keys coming back from a Matrix-Orbital MX400 series LCD display and
keyboard.

I used the "keypad_test_mode" to find out what character is returned for
each key on the keypad, and tested with those keys when using the curses
driver. This reads and processes all keys input from the keyboard properly.

When I change drivers to the MtxOrb, then only the two defined keys work
(Escape and Enter dedicated to the menus). Other keys are not returned to my
application as they are when running the curses driver. How do I read the
keys from the MtxOrb driver?

Thanks,
Eric
