python2.7写的一个串口通信助手 (python serial )

C#编写的串口数据采集器，实时动态显示曲线！这是个一个医疗器械做的一个测试工具！还不错！动态显示动态保存数据！(C# prepared by the serial data acquisition, real-time dynamic display curve! This is a medical device to do a test tool! Pretty good! Dynamic Display Dynamic saved data!)

MSComm控件串口通信编程，第一次作业。(MSComm control serial communication programming, the first operation.)

从事Profibus的开发人员可以利用改源代码理解profibus协议。添加除通讯以外的代码，很快可以开发出自己的智能节点(engaged in the development staff can use the source code to understand change Profibus agreement. Add except communications code, we will soon be able to develop their own intelligent nodes)

十六进制向十进制转化的程序，可用于串口通讯编程。(Hexadecimal to decimal conversion program can be used for serial communication program.)

C#写的控制串口继电器模块的代码，通过发送指令来控制多路串口继电器的开关。(Serial port control relay module C# to write the code, switch by sending commands to control multiple serial relay.)

VC串口通信modbus协议源代码,测试可用。(modbus通信协议)(VC serial communication protocol source code modbus)

一个实用的串口接受程序，希望对大家有用，同时希望大家都能提供一些有用的东西(Serial port to accept a practical procedures useful for everyone, at the same time I hope people will provide some useful things)

串行端口的数字输出控制，本程序使用两个按钮使得用户通过按钮控制DTR和RTS的引脚电压。(Serial port of the digital output control, the program allows users to use two buttons through the button control DTR and RTS pin voltage.)

说明：  自己编写的变异的modbus，先分享给大家(the modbus by myself,now give all)
