Ａは送信動作すなわち情報の伝送の段階にはいる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to information exchange between information transmission apparatuses connected via a transmission line, and particularly to an information transmission system in which data is transmitted using only information data and response data. For information exchange between information transmission devices A and 8 connected via a conventional transmission line, when data to be transmitted is generated in information transmission device A, a signal cut NQ indicating a transmission request is sent to the other party's information transmission device (hereinafter referred to as the transmission device). When the transmission device B is ready for reception, the transmission device B sends an ACK to the transmission device to notify that it is ready for reception. Upon receiving this ACK, transmission device A enters the transmission operation, that is, the stage of information transmission.

置ＢはＮＡＣを送信してそのデータの再送を要求する。The information data is transmitted sandwiched between STX indicating the beginning of data and ETX indicating the end of data, and is sent to transmission device B.
Each time it receives them normally, it sends an ACK to confirm. When detecting an error in the transmitted data, transmission device B sends a NAC to request retransmission of the data.

情報データ交換は、情報伝送方式が複雑かつ、伝送時間
に無駄があった。When the transmission of the required data is completed, transmission device A transmits an EOT to notify transmission device B of the end of transmission, which causes transmission device B to also transmit an EOT, and transmission device A confirms the signal and transmits the series. The information data exchange ends. Like this,
Information data exchange performed using transmission control characters such as ENQ, ACK, etc. requires a complicated information transmission method and wastes transmission time.
