运用VB实现微机与80C31单片机的串行通信

A New Method of Serial Port Communication between Microcomputer and 80C31 Single- chip Computer by Using Visual BASIC

运用 VB的串行通信控件 mscomm，实现 PC机与多台 80C31单片机系统间的通信。在 PC机与单片机的连接中采用了 RS－ 232与 RS－ 485转换器，实现较可靠的长距离通信。

In this paper we discuss the details of communication between microcomputer and 80c31 single- chip computer by using VB,and give the source program and its flowing chart.
