摘　　要：目前 ,在通信领域里 ,一对一的通信方式已经远远不能满足人们设计的需要 ,多机通信已经成为通信控制领域的主流通信形式。通过对MCS - 5 1系列单片机串行口的研究 ,简要阐述了单片机通信方式及串行接口的原理。通过实例 ,介绍了单片机串行口的异步多机通信的应用。At present, the point-to-point communication mode has not been satisfied with the needs of our designs in communication field. Multitude machines communication has been become the mainstream of the communication mode. By studying the serial port of the MCS-51, this article briefly expatiated the single chip microcomputer communication mode and the theory of the serial interface. With some examples it introduced the use of single chip microcomputer serial interface in asynchronous multitude machines communication.
