Hello,
Since several weeks, I search to run BRLTTY with driver Baum.
Unfortunately, it seems that it doesn't work. Indeed, BRLTTY crashes
constantly when I using keyboard.
A long series of beeps are emit, the connection with the VarioUltra is
lost, and I have to kill and restart the BRLTTY if I want to find the
braille again.
Sometimes, this happens just A Few Seconds After Starting BRLTTY without
any action on my part.
I don't have this problem with my old braille display.
Below any excerpts from a BRLTTY log:
