Computer terminal device for producing different types of buzzer sounds

摘要

A plurality of buzzer sound data obtained by converting different types of intermittent buzzer sounds to numerical values is stored in a buzzer source data memory. Coded data received from a host apparatus by a receiver is decoded by a receiver. A decoding result is stored in an index register. The buzzer sound data is read out from the buzzer sound data memory in response to the decoding result data in accordance with the instruction supplied from the host apparatus through a readout. The intermittent buzzer sounds corresponding to the readout buzzer sound data are produced by a buzzer unit.
