适合于工控条件的串行口双向通信

Serial Bi-directional Communication for Industrial Control Application

本文从异步串行通信的基本原理入手，分析在工控条件下通信失败的一些原因，最后给出了一种可靠的串行口双向通信方法。

According to the principles of asynchronous serial communication, this paper analyses the causes of communication failures under some industrial control occasions,and presents a reliable wav for serial bidirectional communication.
