[BRLTTY] Use BRLTTY under Windows 7 with Virtual Braille device

[Siju Samuel]

something similar I did few months back in windows7 and brltty. Though to
share if it helps in anyway.

If you have a pre-built binary or compiled code from source,  then used the
following to start brltty with xw driver.   I was told to
use"no-release-device", for the virtual screen to be shown".

.\bin\brltty -b xw -xno -p none -A auth=none -B model=normal -l debug  -n
-e --no-release-device > debug.log 2>&1

when running the above, I was able to do brlapi call too. Note that I did
not install brltty, instead used pre-built binaries OR compiled from source
I mentioned above

As a note, it can  just emulate only three standard display  using model
values as normal, and two other values.  Also, the current emulator does
not support braille input correctly.    As it has 6 separate dots; but no
option to input more than one dots (like b, c etc) simultaneously.

As part of the prototype work, I have used  brailApi call from our
'software' to display braillle in xw-emulator and also in real display
devices.


thanks,Siju samuel
