串口通讯调试代码，包括端口设置界面和信息收发界面(Serial communication debugging code, including port settings interface and messaging interface)

用VB编写的FX系列PLC通信动态链接库,用户只需调用API函数就可以简单的实现串口通讯(VB prepared by the FX series PLC communication dynamic link library, Users only need to call API functions can be achieved by a simple serial communications)

vC++做上位机实现串口通讯，符合RS485通信协议(vC++ do PC Serial communication line RS485 communication protocol)

vc++写的串口通信程序，对于学习串口通信会有很大的帮助(vc++ write the serial communication program, learning serial communication will be of great help)

用vc写的向串口发十六进制数据。 文件中有整个工程文件。(Vc wrote with hex data sent to the serial port. File in the project file.)

Visual Basic基于天平称重，串口接收数据，在窗体上进行曲线显示(Show Curve)

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)

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

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.)

通过串口读取GPS的信息，并解析信息，显示经纬度以及其他的一些主要值，并将该经纬度值转化成大地坐标值(Read through the serial port GPS information and analysis information to display latitude and longitude as well as some other major value, and the latitude and longitude values converted to geodetic coordinates)
