接收器必须具有某种方法能够知道数据流中字节的起始和结束。在异步通信中，字节边界由起始和停止位指示。在同步通信中，定时机制帮助发送器和接收器处于同步状态。-The receiver must have some way to know the data stream in bytes of the start and end. In asynchronous communication, the byte boundary from the start and stop bit instructi

一个探究VC++ 异步通信原理与实例的代码，程序同样是基于C/S结构的，分服务端与客户端，程序运行效果请看截图。-A VC++ asynchronous communication principle and examples of the code, the program is also based on the C/S structure, sub-service and client, the program run the results see screenshots.
