摘要
介绍了一种仅用单片机串口（ＲＸＴ，ＴＸＴ）同调制解调器进行连接实现远程数据传递的通讯方案，该方案使用单片机资源较少，特别适合于现有仪表的改造。本文还介绍了为保证数据传递正确而提出的类ＸＭＯＤＥＭ协议。实际应用表明本方案实现简单、可靠，是一种较有价值的方案。
A technical proposal for long-distance communication with MCS -51 single chip process and MODEM is developed.It only employs the serial port in MCS-51 single chip process,so it is compatible to improve exitiog instrument for long-distance communication.A communication protocol is introduced for assuring data transmission.The fact has approved that the proposal is sample and credibility.
