Hello,

TIOCSTI is used daily by people typing on a braille device.  The brltty
daemon uses TIOCSTI to synthesize the keypresses.  Yes, it can also
use uinput (and it does) but not in all case: uinput doesn't permit
to synthesize an 'A' (I really mean an ascii 'A', not the key whose
physical position is the position of 'A' on a qwerty keyboard).
