mscomm

可以向串口发送数据，或从指定串口接收数据　VC源码-基础编程-源程序代码免费注册下载(Can send data to a serial port, or from specified serial ports receive data source-basic programming VC-source code downloaded free registration )

Wincc使用MSComm控件串口通讯，VB中发送十六进制数据(Wincc uses MSComm control to communicate through serial port and sends hexadecimal data in VB)

说明：  用数据库实现串口通讯的源代码，功能比较强大，值得一看。(database using serial communication source code, functions more powerful overseas.)

通过和OMron PLC通讯，实时监控自动化设备运行，并下发指令控制(Through the communication with OMron PLC, real-time monitoring of automatic device operation, and instruction control)

QT开发的能够接收串口数据并将其转化为波形同步实时显示的上位机(QT development can receive serial data and converting it into waveform synchronous real-time display of the upper machine)

国外经典的TCP转串口的程序,VC++编写,有较强的参考价值(Foreign classic TCP to serial program, VC++ write, there is a strong reference value)

几种常用的串口调试软件，注意：那个sscom32不能使用奇偶校验(several serial test programs)

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)

DLT645的数据读取,设置串口，后期可能通过数据库读取(read for DLT645 electric)

经典VC++环境下从串口读取数据并实时绘制曲线图(Read data from the serial port classical VC++ environment and real-time rendering graph)
