音视频矩阵的串口控制程序，可以实现8进四出的控制。同时提供了udp监听，接收网络命令，实现网络上控制音视频矩阵。需要用到著名的trayicon控件和mscomm控件-audio and video matrix of Serial control procedures can be achieved eight into four control. While providing udp eavesdropping, the receiving network orders network control audio and video matrix. The need to resort to the famous trayicon controls and controls mscomm

通过rs232，发送一条消息到另一端，可以打开端口，检查打开后才输入消息。

在vb中用字符串的形式来处理串口协议，具有一定的通用性！本程序用来控制伺服电机，调试通过！-vb used in a string of serial form to the agreement, which have a certain commonality! Procedures used to control the servo motor, debugging through!

利用新型单片机c8051f020进行的编程，该单片片机具有很高的性价比。-new SCM C8051f020 use the program, the single pieces of the machine has a price.

串口编程调试精灵，VB实现，绝对经典。可以任意改动。保你赞不绝口。-Serial Programming Debugging genies, VB, absolute classic. Can be arbitrarily changed. You full of praise.

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!

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.
