[BRLTTY] Slowness of some brltty commands

[payman shaykhmehdi]

I think I have used default timeouts, the only timeout value that I have
used in braille display driver is the input of probeBrailleDisplay()
function (==1000).

readBraillePacket() function have been used for reading packets from
device. There is no such delay for DOT keys or keys that are mapped to
Desktop keyboard keys (e.g KEY_BACKSPACE, KEY_CURSOR_UP, ...) but when I
press keys that are bounded to FWINT, braille display reacts slowly.

Is it reasonable to say that because keys such as DOTs and KEY_BACKSPACE
don't execute any command, brltty can handle them faster and so updates
braille display faster?
