[BRLTTY] BrlAPI on Windows

[Matt Campbell]

Hello:

Thanks in part to Samuel's quick work on the Windows implementation of 
the XWindow braille driver, I've decided to use BRLTTY to add braille 
support to System Access, Serotek's screen-reader-like product for 
Windows.  (Yes, we do intend to respect the GPL, by making source 
available for the version of BRLTTY we use, including any modifications.)

The plan is for our product to spawn its own copy of BRLTTY and use 
BrlAPI to control the braille display.  But if I understand correctly, 
on Windows, a BrlAPI client can only be active in one window -- the 
window whose handle is passed to brlapi_enterTtyMode.  But our client 
needs to be active for all windows, except for console windows which 
BRLTTY itself can handle quite well.  What's the best way to achieve 
this?  One solution which occurred to me is that if the client passes 0 
to brlapi_enterTtyMode, then the client would be active for all windows 
except console windows and other windows that have BrlAPI clients 
associated with them.  Are there any problems with this solution?  I 
wouldn't mind implementing it and submitting a patch.

Thanks.
