Abstract

PURPOSE:To attain the transfer of a binary data in a start-stop synchronization system serial data transmission by providing a final data recognition signal line. CONSTITUTION:The data transfer from a transmission/reception equipment 1 to a transmission/reception equipment 2 is executed through a data line 3. A control signal line 4 for control signal is provided in addition to the data line 3. Further, a final data recognition signal line 5 through which a final data recognition signal EOI informing the end of data transferred from the transmission reception equipment 1 to the transmission reception equipment 2 is provided. Only at the sending of the final data, the sender side makes the final data recognition signal EOI active. The reception side detects the final data recognition signal EOI to recognize the data to be the final data.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はシリアルデータ転送方式に関し、特に調歩同期
式のシリアルデータ転送方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a serial data transfer method, and particularly to an asynchronous serial data transfer method.

〔従来の技術〕[Conventional technology]

従来、調歩同期式のシリアルデータ転送方式は、データ
を転送する再装置間に、データ線と制御信号線があった
が、最終データであることを通知するための信号を送出
するための信号線はなかった。Conventionally, in the asynchronous serial data transfer method, there was a data line and a control signal line between the devices that transferred data, but a signal line was used to send a signal to notify that the data was final. There was no.

（：発明が解決しようとする問題点〕 上述した従来のシリアルデータ転送方式は、最終データ
であることを通知する信号の信号線が存在しないので、
コード化されたデータ転送（例えば、ＡＳＣＩＩコード
）の場合は最終バイトを認識できるが、バイナリデータ
転送においては最終バイトを認識できない。(Problem to be solved by the invention) In the conventional serial data transfer method described above, there is no signal line for the signal to notify that the data is the final data.
For encoded data transfers (eg, ASCII code), the last byte can be recognized, but for binary data transfers, the last byte cannot be recognized.

あり、その結果ＣＰ　／　Ｍ上でのバイナリデータ転送
は不可能になる。For example, when transferring binary data between devices with CP/M, if control) roll Z (IAH> in hex code is present in the binary code, the receiving side will stop receiving and return to the prompt state. CP/M specification, resulting in binary data transfer over CP/M being impossible.

このように、従来のシリアルデータ転送方式は、バイナ
リデータ転送が不可能であるという欠点がある。As described above, the conventional serial data transfer method has the drawback that binary data transfer is not possible.

本発明の目的は、バイナリデータ転送が可能なシリアル
データ転送方式ひ提供することにある。An object of the present invention is to provide a serial data transfer method that allows binary data transfer.
