8052单片机和计算机串口通信的试验。已经成功演示，上位机用的是vb写的程序。-8052 single-chip serial communication and computer tests. Have successfully demonstration PC using a program written in vb.

PC串口与PC串口通信，及PC串口调试与单片机通信测试OK-Serial debugging and microcontroller communication

VB 上位机 通过串口与单片机的通信的延时程序，该演示程序包含了普通的串口通信方式，还包含了上位机与单片机通信实例，是个不错的参考-VB host computer through the the serial microcontroller communication delay program, the demo program contains a common serial communication, also contains a host computer to communica

基于单片机的上位机制作，用VB制作的，可以做与单片机通信的参考-PC-based single-chip reference production, VB produced, can be done with the communication of the microcontroller
