摘　　要：介绍了采用智能串行通信卡实现串行通信的原理、结构，以及使之具有通道切换功能的方法。This paper describes an intelligent serial port with channel-switching ability. In this serial port,a micro-processor is just used for serial communication that makes the mast--processor have much time for data-processing.And the channel-switching ability is need when thesystem is important.It can keep the system operating even if any port of the system is failure.
