在VC++6.0中用MSComm控件编程，可以实现串口接收数据和发送数据，数据分别显示在接收框和发送框中。 如何建立工程：建立新文件夹，将文档用WINZIP解压后，双击 Scommtest.dsw 即可在VC6.0中打开工程文件。作者主页上有详细编程说明，每一步都列出来了，可以参考。-In VC++ 6.0 using MSComm control programming, you can realize the serial receive data and send data, data were displayed on the receiver box and sent box. How do I create a project: create a new folder, and will extract the files using WINZIP, double-click Scommtest.dsw can open in VC6.0 project file. Author home page has a detailed program description, list each step, and can refer to.
