C#modbus rtu绝对好用，绝对能用

串口工具，delphi 7 下简单的串口工具源码。(Serial port tools, Delphi 7 under a simple serial source tools.)

RS232的UART编程，包括波特率发生器模块，串口接受模块，串口发送模块(RS232 programming the UART, including the baud rate generator module, serial module to receive, send serial module)

很好的串口通信源程序，可以设置端口号，波特率，数据位 停止位校验位(a very complete source serial communications,it is helpful for everybody)

说明：  很多下位机程序员都有这样的经历，在交付工程的时候对方要求提供源程序，而大多数下位机程序员都知道交出源程序是意味着什么，所以为了保护各位下位机程序员的合法利益.这个工具，伪装过后的源程序可以编译通过。(many lower computer programmers have the same experience that the delivery of the other works on the request source, and most of the next crew to surrender programmers are aware of what it means to the source, Therefore, in order to protect you and lower computer programmer's legitimate interests. this tool, camouflage after the source compile.)

说明：  C#编写的串口通信程序，实现了基本的串口信息配置，收发消息等功能(C# prepared by the serial communication program, to achieve the basic information about the serial port configuration, send and receive messages and other functions)

串口通讯的一个类，已经在用，分享给大家。(serial port communication file.)

利用VISA去控制GPIB串口通信，最终实现与频谱仪，电源，示波器等相互之间通信(VISA to control GPIB serial communication, and ultimately with the spectrum analyzer, power supplies, oscilloscopes, and other mutual communication between)

说明：  串口调试，串口设备模拟，支持32/64位系统。(Serial debugging, serial device simulation)

用vb6.0做的一个小的串口测试程序.可以实现正常通信(Used vb6.0 to do a small test program serial)

说明：  qtserialport官方库，支持qt4安装(qtserialport official lib)
