用VC控件MSComm编写串口通信程序的源代码，并写出详细的编程过程,仅供参考-MSComm control VC prepared serial communication program"s source code, and write a detailed programming process for reference! !

在LPC2106上实现并测试过的代码,用串口收到的数据回显到串口(通过环行缓存实现)并将串口发送的接口写成了printf的形式 -To achieve the LPC2106 and tested code, serial data received echo to the serial port (via the ring buffer to achieve) and serial interface to send written in the form of a printf

使用MSCOMM控件主要是通过事件来处理串行口的交互，即当数据到达时，控件的OnComm的事件就会来捕获或处理这些通讯事件。而OnComm事件也可以用来捕获和处理通讯错误。在实际应用中，一个MSCOMM控件就对应一个串行口，所以如果要处理多个串行口的话，必须有相应数量的控件与之对应。-use MSCOMM control mainly through the incident to the serial interaction, that is, when the data arrived, the control of the incident will OnComm to capture or handle these communications incident. OnComm incident which can also be used to capture and handle communication error. In practical application, a corresponding MSCOMM control on a serial port, so if we are to handle multiple serial port, then there must be a corresponding amount of the corresponding controls.
