说明：  　使用Delphi7、SPComm控件写的一个简单串口调试助手，把源代码分享给大家，在Delphi7环境下调试通过。程序可设置CoM端口，波特率、数据位、校验、停止位等，点击“打开串口按钮”，即可看到状态。
(Using Delphi7, SPComm controls write a simple serial debugging assistant, the source code for everyone to share in Delphi7 through debugging environment. Program can be set CoM port, baud rate, data bits, parity, stop bits, etc., click on the " button to open the serial port" , you can see the status.)
