The beeper device is called beeper.

You can request the beeper to play a sound using the play method :

  play(frequency, time);

frequency is an integer between 200 and 14000, which is the frequency of the sound. time is an integer, which is the duration of the sound in milliseconds. A duration of 0 is infinite.

The command returns immediatly. If you want to wait until the end of the beep, use :

  { beeper.play(myFrequency, myDuration) & wait(myDuration) },
