Modbus_COM

visual c++ 很好的程序例子，适合网络编程初学者编程学习(visual c++ examples of good programs, programming for beginners to learn network programming)

使用NMEA0183的gps服务程序原码(use of a GPS NMEA0183 service program source)

用于监控PLC，针对的是modbus协议(monitoring PLC with modbus protocol)

上位机与三菱PLC之间进行TCP/IP通讯(communication between PC and PLC)

实现使用music算法进行频率估计，并绘图(Achieve the use of music algorithm for frequency estimation, and graphics)

基于UDP通讯服务器的开发，主要负责接收传感器发送上来的检测数据，校验后解析（ＣＲＣ校验），并存储在ＳＱＬ数据库中。(UDP communication server-based development, primarily responsible for receiving the sensor sends up the detection data checksum (CRC check) after parsing, and stored in an SQL database.)

在VC++6.0中用MSComm控件编程，可以实现串口接(used in VC 6.0 MSComm programming, serial port access can be achieved)

计算机网络实验做得串口，非原创，只是为了下载方便。(Computer network experiments do serial port, not original, just for download convenience.)

调试串口很有帮助，用windowsAPI编写，避免了com控件的局限性(help for serialport debug)
