When transmitting data to the center device using an acoustic coupler, first , call the s * center on the telephone, set the handset to the wig, and send out the activation signal for the center connection by one operation.The center device receives the activation signal sent from the acoustic coupler. The signal O validation is performed, and if there is no error, the data IO damage that is subsequently sent is performed, escape is performed according to the content of the data, and the 1# & ring result is transferred to the acoustic coupler.

されるロングスペース信号を待つ。When I called the center at Konin and set the handset to the Kabutsu part after 9 minutes, the human voice and the 5 CTA sound became noise, and the center equipment [K was sent before the activation signal. The parity check is performed by considering noise as a starting principle, but since a parity error is detected, data IO reception that is sent later cannot be performed. This purpose is to detect the O call from the telephone at the center device, and then detect only the #center loading O start signal transmitted from the acoustic coupler in the center device, and to detect the start signal. This is achieved by a data transmission method that receives data from the Mukuonman coupler after the detection of the data. The present invention will be explained below based on examples. , In the figure, AC8 is an acoustic coupler, POS is a telephone, Ex is a switch, MOD is a modem, and NC

The control value CB long space detection means LsD detects the long space and waits for the long space signal transmitted from the acoustic coupler C8.

雑音の影嚇ｔｚけなくなる・When the Ronxshape detection means LJD detects the inner space, the control device C8 outputs the O read command FtEta in the main memory scale MAL. Performs parity check (check (2) in path PR and transfers the data to the specified address in the main memory MS4D. Then, when the end of text signal (ETX) e is received, data O transfer is terminated. According to the original @, when receiving a long space injury, the baritimetta is not performed, and the attacking space itself is used horizontally, so the shadow of the noise will no longer be felt as in the past.
