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!)

说明：  VB做的一个短信收发的例子,功能比较强大,可以好好参考(VB do an SMS transceiver example, function more powerful and can make reference to)

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)

一个简单的VB串口发送程序,初学者参考.(a simple VB Serial this procedure, beginners reference.)

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)

用VB编写的FX系列PLC通信动态链接库,用户只需调用API函数就可以简单的实现串口通讯(VB prepared by the FX series PLC communication dynamic link library, Users only need to call API functions can be achieved by a simple serial communications)

利用VB语言实现对串口进行操作，从而实现通过串口进行远程关机的操作，了解相关编程方法。(VB language serial port operation through the serial port for remote shutdown operation, understanding related programming methods.)

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)
