Control-C is a special keyboard character caught by the terminal drivers. It passes the SIGINT to the foreground process. While it's easy to ignore this single character sequence as shown above, it may be better to use Curses to ensure that you ignore ALL input while your loop is running. Also, Curses can help you to "beautify" your output. Also, you could assign ^C a subroutine or some instructions to notify the user that the key is being ignored. The C docs will help you more than the perldocs, so look at man curs_inopts(3X). Good luck!
