[erlang-questions] Reading (and ignoring) escape-sequences

I suggest you to learn termcap/terminfo libraries on UNIX,
and the curses library (ncurses now I guess) source code.
You need to parse the whole sequence anyway.
And the definition of those sequences depends on the type to
terminals you're going to connect.
