Command beep

Emit a short tone through the internal buzzer.

Synopsis

beep

Ordinary invocation: foreground child, PID 3; the shell waits. Not an allowed pipe producer.

This command has no documented parameters.

Uses the kernel’s bounded shared-controller transaction and then releases the controller. It accepts no pitch or duration argument.

beep

For programmable raw sound parameters in a BASIC application, use SOUND. For periodic background beeps, use RUN PULSE.

Success is status 0. No command-specific status is added; shared ROM/controller failures remain possible. See the diagnostic reference.
