modbusRTU Communications with RS485

用VC++实现的一个测试通信系统的误码率的程序，很好用的，是用两个串口的数据测试误码率的。(With VC++ realize a test communication system BER procedures, very good use, with two serial test data error rate.)

vc6.0 使用NTGraph控件 读取串口数据后画出波形图(vc6.0 use NTGraph read serial data control to draw waveforms)

说明：  串口编程调试精灵是一种串口编程的调试精灵(Wizard is a serial programming and debugging, the debug serial port programming wizard)

本程序调用了微软自带的mscomm控件，实现com口的数据接收，读者可自行添加发送数据功能。内附mscomm.ocx控件及其注册方法，本程序是用的静态链接库，为的是能在没有vc库的机器上也可以运行，所以个头大了点。(Microsoft's own mscomm controls, I realize com data reception, readers can add their own functions to send data. Enclosing mscomm.ocx control and registration method, the procedure is used in the static link library, for the in the absence of vc for the machine can also run, giving the larger point.)

实现串口通信的编程，关于类以及继承的一些使用方法，新手可以参考。(Serial communication programming, use classes and inheritance, the novice can refer to.)

通过和OMron PLC通讯，实时监控自动化设备运行，并下发指令控制(Through the communication with OMron PLC, real-time monitoring of automatic device operation, and instruction control)

串口收发字符型,没有选择COM口参数，固定为COMPROT 3 115200(Serial transceiver character type, no choice of COM port parameters, fixed to COMPROT 3 115200 )

经典VC++环境下从串口读取数据并实时绘制曲线图(Read data from the serial port classical VC++ environment and real-time rendering graph)

说明：  通过CreatFile SetupComm GetCommStat等API函数来创建一个串口传输程序(CreatFile SetupComm GetCommStat such as through the API function to create a serial transfer procedure)
