C#写的控制串口继电器模块的代码，通过发送指令来控制多路串口继电器的开关。(Serial port control relay module C# to write the code, switch by sending commands to control multiple serial relay.)

一个串口写卡程序，能够读卡片显示内容，很好用的。(A serial write card program that can read the card display, very good use.)

另一个基于s3c44b0x的串口测试程序,用的是三恒星的s3c44b0增强型开发板(Another serial based on s3c44b0x test procedure, using a three-star s3c44b0 enhanced development board)

使用labview2011编写的串口采集程序，可以自动保存采集数据，并自动按创建时间分类。生成的txt文档可供matlab等软件进行后续数据处理。(Use labview2011 prepared by the serial acquisition program, you can automatically save the collected data and automatically classified by creation time. Txt files generated by matlab software available for subsequent data processing.)

实现海康硬盘录像机或摄像头的录像拍照等功能的DELPHI源码(DELPHI Source Code for Realizing Video Capture Functions of Haikang Hard Disk Video Recorder or Camera)

串口通信程序,如果有问题可与本人联系，大家一起讨论讨论 (series communction)

This is the source code for I2C(Inter Integreted Circuit) which is used in serial communication

Huffman编码和解码程序,用c++编写,健壮性强,值得参考()

VB开发的串口通信源码。对端口速度、奇偶校验、停止位等都可以设置。用于串口通信的开发(VB source of serial communications. The port speed, parity, stop-can all be set up. Serial Communication for Development)
