Doing tty/terminal stuff using the normal erlang i/o function is hard
or even downright impossible.
Your best bet for tty stuff is to use my slang interface which
available at http://erlang.org/user.html
This is a one 2 one mapping between erlang and the slang tty functions.
(slang is a general purpose portable tty library)
On ther other hand, since you said that you were actually learning erlang
just right now, the slang library may be a bit hard to use.....
