VCPP-Code4

cai yong 一个串口拓展成4个串口！(1 uart to 4)

Ymodem传输，基于VC6，可以当串口调试(about Ymodem)

说明：  调试使用的串口助手，程序源码，功能齐全，可以调试程序(Serial Port Assistant for Debugging, Program Source Code, Full-featured, Debugging Program)

调用WinAPI函数进行串口通信，并且应用了多线程技术启动工作线程对串口的输入进行监听(call WinAPI serial communication functions, and uses multi-threading technology to activate the working threaded serial input eavesdropping)

几种常用的串口调试软件，注意：那个sscom32不能使用奇偶校验(several serial test programs)

说明：  串口通信高级编程提供了一个能够进行串口通信的类，能够方便地进行各种数据通信。 由于本程序设计到硬件编程，因此，如果读者的串口通信设备 没有连接好，可能会有问题 (Serial communication provides a high-level programming to carry out the type of serial communication, the ability to easily carry out a variety of data communications. Since the hardware design to programming, so if the reader' s serial communications equipment is not connected well, there may be some problems)

这个程序是利用VC编写的一个从机串口响应modbus查询命令程序，实现RTU方式，3.5和1.5个字符时间检测，CRC和LRC校验。(This program is written using VC as a response from the machine serial modbus query command procedure, to achieve RTU mode, 3.5 and 1.5 characters time detection, CRC and LRC check.)

网上整理下载的非常好的串口程序，功能强大，代码质量也很高。(About serial communication)

this is visual c++ 6 project it is a Serial port excerszier software

VC实现和S7-200PLC的串口通信程序,很有价值哦(VC and S7-200PLC Serial Communication Program and of great value oh)
