串口通讯类，支持异常处理，Overlapped 和 Block 传输，支持Unicode...

用于VC的DLL库，使用异步通讯方式，具体使用方法请看源码-for VC DLL libraries, the use of asynchronous communication and the use of specific methods Look at source

C++ Builder模拟RS232设备XONXOFF软件流量控制信号，包括源代码可以更基本为7。

将串口通讯协议存储为一个通讯文件，可是随时将存储通讯协议文件调入计算机运行与下位机通讯可以实现通讯对话，-Serial communication protocol will be stored as a communications document, but to keep the communication protocol storage document transferred to the computer is running and the next-bit machine communication can realize communication dialogue
