Description: 本程序在serialport的基础上修改.
１. 加强了串口发送纠错能力，为串口拔插后的再连接提供了可能．
２．提高了串口接收的效能，由以前的查询方式接收改为由事件驱动
接收，在没接收数据时不占用CPU时间．
３．修改了１６进制发送时只能发送大写的A--F,改后大小写a--f都
能发送.
４．修改了１６进制发送时不能输入空格的毛病．
５．修改了接收大文件时，程序反应迟钝的毛病．-This procedure in the basis of serialport modify .1. Strengthened the serial port to send error-correcting capabilities, for the serial plug to be connected after the possible. 2. Improve the performance of the serial port to receive, from the previous query receive replaced by event-driven receiver, did not receive data when in the off-CPU time. 3. Revised 16 hex is sent only to send an uppercase AF, changed after the case af can send .4. Revised 16 hexadecimal sent should not enter a space problems. 5. Modified to receive large files, the program unresponsive illnesses.
