[BRLTTY] Alva BC640 perkins input

[Nicholas Dechman]

Ok, I have my firmware version.  The do not make this easy for sighted people :-D

The firmware menu item reads:

Firmware: 2.10.0 BT 1.20.0 1.4.0


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.

I'm using BrlTTY on windows, in case I forgot to mention that :)

Having BrlTTY capture the keystrokes is what I want, because I want to be able to handle control keys outside the application that is using the braille display.  BrlTTY does not appear to be capturing any keys, however, and the keys are not appearing as standard keyboard input either.  The just vanish.

I am still getting used to the menus on this thing and I read braille very slowly, so it's gonna take me a bit to get the firmware version.  Unless there's a sneaky way to find the firmware version without navigating a bunch of menus on the device :)

I can't help with this, but there have been issues discussed on the list with
different versions of Alva's firmware. Which version are you running?

Also,
 does the keyboard appear as a human input device to the USB interface?
If so, then it really should work, since this is supported at the operating
system level rather than by BRLTTY. I suppose you could make sure that BRLTTY
isn't intercepting the keyboard just to eliminate that variable from the
situation.
