自己编写的串口通信上位机。一直工程在用，其中的发送数据我已经做了修改！...

本文详细地介绍了在Win32环境下通过调用通信API 函数以异步方式来实现PC机和MCS 51 单片机之间的通信过程给出了软硬件设计机理以及详细的通信协议说明-This article described in detail in the Win32 environment by calling the communication API function in order to realize asynchronous approach to PC and MCS 51 Singlechip give the communication process between the design of the mechanism of the hardware and software as well as detailed description of the communication protocol

Simple UART with 8x clock

这是我做的关于考勤机的一些测试程序，请大家积极下载，很有帮助。-This is my appraisal done on the plane of some testing procedures, please download positive and helpful.

用vb实现串口间通信,可以用来熟悉串口间传输信息的原理.-with Serial Communication, which can be used with serial transmission of information between the principle.

串口实现双机互联，经典的小程序，经过多次调试，绝对能运行。-Serial Port-machine Internet, the classic small procedures, after many tests, can certainly run.

实现字符转换！需要在两台机子上运行，也可以把一台机子的两个com口连在一块！这样就行了！还需要一个串口调试程序，网上可以下载到！-achieve characters change! The need to run two machines, one Taiwan can the two com loom even in a mouth! So OK! Need a serial debugging procedures can be downloaded to the Internet!
