很有名的串口类，功能封装的相当完善易用，其中还包括了流控的设置...

ABB AIN电表对数据类11解码的例子程序-ABB AIN meter 11 categories of data decoding procedures example

这个是串口的基于停止等待协议原理编程，这个是接收程序，很好用哦-this is the agreement on principle to stop waiting for the program, this is the receiving process, oh well spent

一个简单实用的串口类，用起来非常方便。直接使用类。-a simple and practical serial category, and it is very convenient. Direct use category.

实现串口的通信功能-Serial communication function

我用vb编写modbus协议,拿出来与大家分享一下，厚厚，希望得到大家的指教-Modbus protocol prepared hard to share with you some thick hope to enlighten all

用从c++编写的串口通信程序，内有详细的了解并设置串口参数的源码，并含通信原理-prepared from the use of serial communication program, with detailed understanding of serial port parameters and set up the source code, and communication with Principle

本文详细地介绍了在Win32环境下通过调用通信API 函数以异步方式来实现PC机和MCS 51 单片机之间的通信过程给出了软硬件设计机理以及详细的通信协议说明-This article described in detail in the Win32 environment by calling the communication API function in order to realize asynchronous approach to PC and MCS 51 Singlechip give the communication process between the design of the mechanism of the hardware and software as well as detailed description of the communication protocol
