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)

串口调试助手，适合做串口通讯的人员使用。VB.NET编程。(vb.net serial debug for usart comm.)

VC++之MFC串口,包含串口调试助手源程序 及编程详细过程 (MFC serial port)

串口通信，采用CRC16 算法，用mscomm控件实现对chp500电源的信息采集，可以设置电源的电压和频率，word文件的是通讯协议，上位机发送和下位机返回，串口通讯看懂了通讯协议就没什么问题的啦。(Serial communication using the CRC16 algorithm, mscomm realize chp500 power control information collection, you can set the voltage and frequency, word document is the communication protocol, host computer to send and return lower machine, serial communication protocol is very important to you)

串口调试，串口设备模拟，支持32/64位系统。(Serial debugging, serial device simulation)

使用MSCOMM控件，实现两台电脑通过串口进行通信的功能。(Use MSCOMM control, to achieve two computers to communicate through the serial port function.)

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)

基于VC实现的串口通信，可以实现串口的数据读取。(Based on the VC serial communications)

这是MFC串口编程的具体步骤 对学串口编程有很大帮助(This is the MFC programming serial port programming of specific steps to learn of great help)

希捷硬盘维修软件，通过COM口与硬盘通信，进行ROM和固件的读写，开启工厂自校准进行固件和坏道的自动修复。(Seagate hard disk repair software, communicate with hard drive, through the COM ROM and firmware, speaking, reading and writing, open the factory since the calibration for the firmware and bad auto repair.)
