Moreover, I have experienced complete freezes with brltty 5.0-2ubuntu2
on Handytech devices (ancient Modular 40 and Braille Star 40). Suddenly,
the contents displayed on the braille terminal wouldn't update, no
matter what keys I press on the regular keyboard of the computer, until
I press (I think) an arbitrary key on the braille terminal, definitely
navigation keys or the „jump to cursor“ key. I'm not sure though,
whether this is really related to the issue discussed here.
