[BRLTTY] brltty and liblouis

[John J. Boyer]

Hello everyone,

I'm Using the UEB Grade 2 liblouis table in Orca. A while ago i made a pleasant discovery. 
I can give the brltty keystroke on my Braille display for 8-dot computer Braille and I get it in Orca. When I give the keystroke for 6-dot Braille Orca goes back to UEB.
