It seems that Fletch has provided you with a workaround. If you are interested in a more formal solution, you will find that it is probably system dependent. Start by reading getc and Term::Key.

UPDATE: I found the link to Term::ReadKey in the documentation of getc. It appears to have useful info. Sorry for the error in posting the link.
