2、通信，在实现多机通信时主机向三个从机发送各自的从机号与数据，而 在实现双机通信时，则是从机向主机发送从机自己的从机号码。 关键词：MCS-51 单片机 串口通信 双机与多机通信 Abstract This graduation thesis discussed the typical of dual machine and multi-machine communication of MCS-51 Microcontroller. In the article, when explaining the structure of Serial Port, the theory of Serial

3、 Ports Works, the manner of Serial Port Working and Serial Port communication, I acquired the basic knowledge of Serial Port communication. Thus I could design out the hardware and software that were able to realize dual machine and multi-machine communication function. In this thesis the design of

4、dual machine and multi-machine communications method of Serial Port communication was half-duplex communication, which all had the abilities to send and receive data. But at the same time only one sent and other received. My thesis introduced the Serial Port communication that was one host computer and three dependent machines, when multi-machine communication worked that sent the own number of slave and data to th
