OK, got it, thanks for clarifying.

In the long run, I think uncontracting should really not be done inside
of a braille driver because it is not a driver-specific thing.

Now if it is only for tests, cou might be able to do it in readCommand
as you propose but that looks as a lot of work, too.

If it is only for testing purposes, you could also write a BrlAPI client
that reads the keypresses and interprets them with the help of liblouis.
Of course the uncontracting feature would then be available only in this
client but it may be enough for testing.

hth,

Shérab.
