[BRLTTY] Alva BC640 perkins input

[Nicholas Dechman]

I just ran a much more careful test.

I plugged in the alva and turned it on -- keyboard input works
I started BrlTTY - keyboard input does not work
I started my application which uses BrlAPI to take control of the device - keyboard input does not work but braille output does work
I stopped my application and left BrlTTY running - keyboard input now works
I started my application again to make sure BrlTTY is really still running, and braille output works but keyboard input does not.

So... That's even more interesting.  It seems to allow keyboard input after I use BrlAPI but not before!

>And I have a little more detail about the behavior.  The alva will still generate keyboard input after BrlTTY is started, but it stops generating them as soon as I take control of the device through BrlAPI.  After this, the keyboard events are not captured by BrlTTY, and if I give focus to another application and try to type some characters, the characters no longer appear.

This is an important piece of information. I believe it probably has to do with 
your BrlAPI application not ignoring the keyboard key ranges so that they'll 
pass through to brltty and be handled as expected. Can you confirm that 
keyboard resonse comes back when you release BrlAPI control.
