PURPOSE:To transmit exactly infrared-ray data by transmitting a code for showing resending data and the same data by containing it in a data constitution, in case data is resent to the receiving side from the transmitting side, when a hand shake error has been generated. CONSTITUTION:In case data ''A'' to which a resending bit ''0'' and the same data bit ''0'' have been added is transmitted from the transmitting side, and a hand shake error which has not been received by the receiving side is generated, the transmitting side puts ''1'' for showing resending data to the same data after a prescribed time and resends it. As a result, the receiving side outputs a receiving signal to a connecting machine from a buffer of a transmitting and receiving unit 4, and sends an ''OK'' signal to the transmitting side. Subsequently, in case the ''OK'' signal sent from the receiving side is not received by the transmitting side, the transmitting side resends the data ''A'' to which a resending bit ''1'' and the same data bit ''0'' have been added, to the receiving side. When it is received by the receiving side, the ''OK'' signal is sent to the transmitting side. |
