Description: advanced pc-speaker beeper
 beep does what you'd expect: it beeps. But unlike printf "\a" beep allows
  you to control pitch, duration, and repetitions. Its job is to live inside
   shell/perl scripts and allow more granularity than one has otherwise. It is
    controlled completely through command line options. It's not supposed to be
     complex, and it isn't - but it makes system monitoring (or whatever else it
      gets hacked into) much more informative.
      Tag: implemented-in::c, interface::commandline, role::program, scope::utility, works-with::audio

in debian stable - try morse code with that ?
