利用windowsAPI（非组建/控件等）编写的comm通信程序库，能够实现comm单字节/多数据发送接收，延时处理等。使用前如不调用.h中的初始化函数，则使用默认频率。.c文件为一个小的测试程序，使用时包含.h即可。-The use of windowsAPI (non-set up/control, etc.) prepared comm communication library, to achieve single-byte comm/data to send more than receiving, processing delay. If we do not call before use. H in the initialization function, then use the default frequency. . c file for a small test program, use contains. h can.
