Simple text user interface question

Vlad and Per,

by the moment I'm not looking for a portable and elegant solution. I'm
working on Windows and tried "\r" with werl.exe yesterday!! But the solution
working in a text shell is enough. Thanks!

One more question: I tried io:get_chars('Input key: ', 1) but it seems to
wait for an ENTER and to cut the read characters to the specified length.
I'm in fact looking for a way to read just N (in this case 1) keys from the
keyboard, *without* waiting for an ENTER. Any ideas?
