1.使用多线程的串口类。有读线程和写线程，发送、接收缓冲区（默认2048字节），满足高性能的收发要求。



2.提供事件通知回调函数接口，可以实现接收的消息接口



3.可以监控Modem事件，提供流控接口。



4.调用接口简单。使用例程参考CommTest.dsw-1. Using multi-thread serial port class. Have read the thread and write threads, send, receive buffer (default 2048 bytes), to meet the requirements of high performance transceivers. 2. To provide event notification callback interface to receive the message interface can be achieved 3. Modem can monitor events, to provide flow control interface. 4. Call interface simple. Use of routine reference CommTest.dsw
