XWP仪表参数的读取，是帮1个朋友编写的(Instrument parameters XWP read, is to help a friend prepare the)

串口通讯调试代码，包括端口设置界面和信息收发界面(Serial communication debugging code, including port settings interface and messaging interface)

该程序是串口调试代码程序,支持大多数操作系统(Serial debugging software source code)

visual basic+数据库access+串口+实时显示曲线(vb+database access+serial)

STRING MATHMATICAL PLEASE COMMENT

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，visual basic撰写，可以发送包括word格式，excel格式，text格式等文件(Serial debugging, visual basic writing, including word format can be sent, excel format, text format file)

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)

转载，自己需要一些串口程序与控件的应用知识，希望能够和大家共同学习，共同进步！(reproduce, they need some serial procedures and controls the application of knowledge, and we hope to be able to learn together. common progress!)

vb 串口上位机 很简单的一个版本，大家自己扩展功能吧 (com executed on pc,it s a simple version ,easy for expansion)
