串口通信例程，内含串口类，一个老外写的，我修正了一个bug：在接收数据流未完成前退出程序会导致进程驻留在内存-Serial communication routines, containing serial port class, written by a foreigner, I fixed a bug: the receiving data stream does not quit the program before the completion of the process will lead to reside in memory

串口收发程序，采用时间触发和事件触发，已经实际应用。-procedures, and use of time-triggered events trigger has practical applications.

用vc自带的插件开发串口通信源程序-vc onboard with the development of plug-in serial communications source

微机实现异步通信是依靠适配器来完成的，而后者又是以UART芯片，即通用异步收发器芯片为核心构成的。 IBM PC的异步通信适配器使用的UART芯片为INS 8250。 -Computer realize asynchronous communication relies on the adapter to be completed, which in turn is a UART chip, which UART chip at the core composition. IBM PC
