个人写的一个串口通讯程序，希望对大家有帮助。

C8051F340单片机双串口同时工作 中断接收数据 查询发送数据-C8051F340 MCU pairs of serial ports simultaneously send data to interrupt reception data query

计算机串口调试的小程序，可以监测串口的RTS,DSR活动-Computer serial port debugging applets, you can monitor the serial port of the RTS, DSR activities

一个很好用的串口类，包括同步、异步等多种调用机制。-a good use of Serial categories, including synchronous and asynchronous transfer mechanism other.

串口 操作 源码 打标机的控制程序，很实用欢迎下载-source Marking operation of the control procedures, practical welcome to download

异步fifo 源程序代码 欢迎大家学习 用VHDL语言编写-asy fifo

串口测试程序，波特率、串口选择等多种功能完善，推荐下载。-serial testing procedures, baud rate, serial choice of a variety of functions, recommended download.

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.
