= 作者    ：謝利洪
= Email   : xiliho221@163.com
= 版本    : V1.1
= 編寫時間: 2006.10.21
= 說明    ：本版本由sky的1.0修改而成，本來只是用來學習SPCOMM控件的，想不到經過一
            個晚上的努力，程序已經近于完善了。就將我的成果共享出來吧。由于改用
            COMPORT控件為SPCOMM控件，整個代碼已經經過大規模的改動，去除了Email等
            與程序應用不太相關的部分，改進了絕大部分算法，添加原未完成的功能 ，程序
            依然是參照龔建偉VC版《串口調試助手V2.2》來編寫的。
