On a tty or in <code>-batch</code> mode this emits a BEL character. In a GUI it does whatever suits the window system. Variables <code>visible-bell</code> and <code>ring-bell-function</code> can control the behaviour.
<code>beep</code> was originally called <code>feep</code>, but that changed, recently :-)
