What, exactly, are you trying to do? This sort of thing shouldn't be hard-coded 
within a braille driver. The proper way to do it is to let the user configure 
status cells to show information like that.

>I tried to use *currentScreen* from *scr.c*, but it always returns 0.

Having braille code depend on screen code isn't good design. For example, even 
if you get something like that to work, you'll have no guarantee that a fugure 
release of brltty will still support it.
