[jawsscripts] AW: best way to display text on braille display?

Hi Thomas,
I'd suggest to do it the following way:
- Configure Jaws to use structured mode for your App.
- provide a Function, Int Function BrailleBuildLine(), that returns TRUE
- in that function use BrailleAddString() to send your data to the display
- BrailleBuildLine() is called by Jaws periodically, so all you have to do
is to update your string variable as needed, maybe either in NewTextEvent()
or from your scripts directly.

It may be necessary to call BrailleRefresh() after you updated your string
variable.

Best Regards, Willi
