Turn on the InputK beep function. It affects the automatically generated beeps plus the KBeep instruction.
On SPLat boards with onboard push buttons, default behaviour is that a short beep is generated when a latched button press is read out by an InputK or related instruction.
This instruction is implemented only on boards that have the appropriate hardware. On other boards it will generate a fatal runtime error.
