Comentarios

De forma predeterminada, el pitido se reproduce con una frecuencia de 800 hercios durante 200 milisegundos.

Beep ajusta una llamada a la función Beep de Windows. Si Beep genera un sonido en versiones de Windows antes de Windows 7 depende de la presencia de un chip de temporizador de intervalo programable 8254. A partir de Windows 7, depende del dispositivo de sonido predeterminado.
