[erlang-questions] terminal codes

[Mazen Harake]

I'm not sure this is 100% relevant to the discussion but if you like you 
can take a look at cecho which is an ncurses library for Erlang. You can 
set terminal modes (like cbreak mode and noecho) etc very easily, it 
also supports colors.

Check it out here if interested: http://github.com/mazenharake/cecho
