modbusRTU Communications with RS485

cai yong 一个串口拓展成4个串口！(1 uart to 4)

基于VC实现的串口通信，可以实现串口的数据读取。(Based on the VC serial communications)

PLC程序，结合VB通信实现两轴运动带减速功能(PLC programming, communication with VB to achieve two-axis motion with deceleration )

这是MFC串口编程的具体步骤 对学串口编程有很大帮助(This is the MFC programming serial port programming of specific steps to learn of great help)

这是串口调试助手，可以显示，并带有图像显示(This is a serial debugging assistant, you can display, and with image display)

串口通信，采用CRC16 算法，用mscomm控件实现对chp500电源的信息采集，可以设置电源的电压和频率，word文件的是通讯协议，上位机发送和下位机返回，串口通讯看懂了通讯协议就没什么问题的啦。(Serial communication using the CRC16 algorithm, mscomm realize chp500 power control information collection, you can set the voltage and frequency, word document is the communication protocol, host computer to send and return lower machine, serial communication protocol is very important to you)

标准串口win32接口函数,通过这些微软提供的串口接口函数可以实现对串口的读写操作(standard serial port debug source code)

基于MFC的强大的串口通信程序，可以用于串口通信测试(Based on the powerful serial communication Demo MFC can be used to test)

串口调试程序源代码，本例作为学习串口编程具有很好的参照作用。(Serial debugger source code, in this case as a learning serial programming with a good reference to the role.)
