串口DLL

说明：  RS232-c串口编程资料收集整理，有C源码实例。 (Serial programming data collected, there are C source code examples.)

使用VS2013的MFC编写的一个简单Modbus RTU的单命令控制Demo，能够实现继电器的开和关(A single command control demo of a simple Modbus RTU written in MFC of VS2013 enables relay opening and closing)

合众达提供的两个驱动，可以添加自己的算法。一个是串口的，一个是实时系统的。(America to the two drivers, they can add their own algorithms. 1 serial port, a real-time system.)

这是一个用C#编写的串口调试程序源码。功能包括普通串口数据收发。以及Modbus两种发送模式校验：RTU，ASCII。 是一个很好的工业控制开发上位机学习入门的学习代码。程序均已调试通过，和测试 (This is a C# prepared by the serial debugging program source code. Common features include serial data transceiver. Modbus two: RTU, ASCII transmission mode check. Is a very good industrial control the development of PC learning introductory learning code. Debugging and testing)

虚拟串口实现图像视频显示 虚拟串口实现图像视频显示(Virtual serial port virtual serial port video display image image video display)

串口调试助手，适合做串口通讯的人员使用。VB.NET编程。(vb.net serial debug for usart comm.)

耀华表通信控件 内置了地磅的串口协议。能自动读取指定的数(Communication control Toledo Electronic loadometer, serial direct source reading program. The source without any Dll, built-in serial port loadometer agreement. Can automatically read the specified binary readings.)

计算机通过串口向开发板发送数据，开发板将数据原样送回。(The computer through the serial port to send data to the development board, development board will be sent back to the data as is.)

说明：  一个含串口访问功能的小测试程序，含多线程，CRC校验 此程序包含了一个串口通讯的类，并能够实现简单的通讯功能，希望对要用API函数写串口通讯程序的朋友有帮助 (a serial access function with a small test program, including multithreading, CRC procedure contains a serial communications category, and to achieve a simple communication, want to use API function to write the serial communication program to help friends)

说明：  modbus很全面很详细的485从机程序。(Modbus is a very comprehensive and detailed 485 slave program.)
