The short answer is "not in a portable way".
The long answer is "you can hack something up, for your own machine and
environment, but it's probably more work than it's worth".
What's needed? Look up your terminal's capabilities, and use them from
Erlang. I did once a small library that used ANSI codes to steer the cursor
and put some colors on the screen. Worked nice, but of course the output
will be jumbled-up on terminals with no ANSI support...
