摘　　要：单片机应用系统中经常要用到一个以上的串行通信接口。本文介绍8031单片机串行接口扩展的一种有效方法,并阐述了利用扩展的单片机串行接口实现与IBM-PC机的远距离通信的实用方法。这些方法均在工业测控系统中得到成功应用。A single-chip computer application system often uses more than. one serial communication interface. An effective extension method of 8031 single-chip computer serial interface is introduced in this paper; And the practical method to realize remote communication between IBM-PC and the extended single-chlp computer serial interface is also presented. These methods have been successfully applied in the industrial measurement and control system.
