说明：  VC++编写上位机串口通信界面，原创VC++编写串口通信上位机界面 本人做接口实验时上位机部分 (VC++ write PC serial communication interface, the preparation of original VC++ serial communication interface, PC interface, I do some PC experiments)

串口字符串发送与筛选接收,一次可以发送字符串和数字串。(Serial string sent with screening reception, one can send a string several strings.)

为了实现对船舶电站的实 时监控，对PLC编写程序，并在LabVIEW作为监控界面的情况，PLC与工控 机之间采用OPC技术实现通讯，GPC与工控机之间采用Modbus串口协议实现 通讯。最后在实现通讯的的基础上，对本系统进行了试验调试，并开发监控界 面。(In order to achieve real-time monitoring of ship power plant, the PLC programming and control interface as in the case of LabVIEW, PLC and IPC communication between the use of OPC technology, GPC and IPC used between the Modbus serial protocol communication. Finally, to achieve communication based on a test of the system to debug, and develop monitoring interface.)

串口通讯类及其例子程序,很有用的串口调试范列(Serial Communication category and examples of procedures, useful for debugging serial Fan out)

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)

初始化RTCM控制，并且把文件或者串口数据转输出成RTCM格式(RTCM control initialization, and the output files or serial data transfer format to RTCM)

串口发送modbus协议CRC校验低字节（若为查表所得数据为高字节，其实为CRC的低字节）(serial modbus connection agreement low byte CRC (if available for look-up table for the high-byte data, In fact, for low-byte CRC))
