我见过最好的串口类

485多机通讯的连接方式，主要有总线方式、星形方式等(connection of multi pc communication with 485)

利用C语言实现RS232串口上下位机通信的设计(Using C language to realize RS232 serial port communication up and down a machine design )

CVI环境下的串口调试助手，主要功能有即时收发信息，显示波形，截图和保存数据(CVI environment serial debugging assistant, the main function includes immediately send and receive information to display waveforms, capture and save data)

基于MFC的强大的串口通信程序，可以用于串口通信测试(Based on the powerful serial communication Demo MFC can be used to test)

串口测试程序 (Test porgram for serial)

VC++环境下用MSComm控件进行串口通讯编程 模型飞机测控平台(VC++ environment serial communication programming model aircraft monitoring platform with MSComm control)

改进后的龚建伟串口调试助手V2.3.exe 的VC++6.0工程源程序(Gong Jianwei serial improved debugging the assistant V2.3.exe VC++ 6.0 project source)

索佳、拓普康全站仪串口通信控制指令，通过软件控制仪器实现联机通信与自动测量。(Total Station Control Command)

485通讯接口模块的编程应用，监控显示，检测报警显示，上下值的设置输入输出的结构(485 Communications Interface Module programming applications, monitor display, alarm detection showed that the whole value of the structure of input and output settings)

用VC++实现的一个测试通信系统的误码率的程序，很好用的，是用两个串口的数据测试误码率的。(With VC++ realize a test communication system BER procedures, very good use, with two serial test data error rate.)
