vb 串口上位机 很简单的一个版本，大家自己扩展功能吧 (com executed on pc,it s a simple version ,easy for expansion)

Visual c++实践与提高——串口通信与工程应用篇10源代码(Visual c++ practice and improve- serial communication and project source code (Application) 10)

用VC++实现的一个测试通信系统的误码率的程序，很好用的，是用两个串口的数据测试误码率的。(With VC++ realize a test communication system BER procedures, very good use, with two serial test data error rate.)

可以向串口发送数据，或从指定串口接收数据　VC源码-基础编程-源程序代码免费注册下载(Can send data to a serial port, or from specified serial ports receive data source-basic programming VC-source code downloaded free registration )

此程序实现了对串口输入的ADC数据和温度数据的实时曲线图显示。(This program realizes the serial input of the ADC data and temperature data in real-time graph display.)

VB和信捷PLC通讯的源代码，包括读写，置位，独一无二哦，网上都找不到的。(vb and thinget plc communication program source,good thing)

说明：  非常好用的串口变成工具和源代码，可以自动搜索串口，有非常高的参考价值。(it is very nice! you can use it easyly, it is Visul C++ code .)

串口温度数据采集并实时显示 读串口数据的原理是,只要当有数据向串口发数据来时,计算机就会自动将其数据写到一个特定的缓冲区,我们只要写程序去读那个特定的缓冲区就可以了. 有数据向串口发过来时,程序可以将数据接收到,接收的数据是字符型的,那么将数据转化为数字型的,再将这个数据的大小作为画图的某一个点的纵坐标,横坐标为数据的序号.将这些点用线连起来就是一个曲线图了,这个就是图形显示基本原理. 查看原来的数据的原理也是这样的,不同的地方就是,数据是从文件中来,同样的也是将多个数据分成一个一个的,然后这一个数据的大小就是画图的某一个点的纵坐标,横坐标同样为数据的序号,再将这些点用线连起来就是曲线图. 图形能移动的原理,是我们首先改变的只是数据,图形并没有变,但图形的形式是由这些数据来确定的,当数据发生变化后,我们通过刷新显示区来变化的.(Serial temperature data acquisition and real-time serial data reading the principle is, as long as when a serial data to the data, the computer will automatically writes data to a specific buffer, we can write specific procedures read that the buffer zone would be fine. Serial data to be sent, process data can be received, the receiving of data is the character, then transform data into digital type, and then the size of the data as a drawing of a point Ordinate, the abscissa serial data. these points will be used to link line is a curve, this is the graphic display the basic tenets. View the original data is the same principle, the difference is, the data from the file, the same data also will be divided into a number one, and then this one is the size of the data to draw a certain point )

CVI环境下的串口调试助手，主要功能有即时收发信息，显示波形，截图和保存数据(CVI environment serial debugging assistant, the main function includes immediately send and receive information to display waveforms, capture and save data)

串口调试助手的源码,自己编写，界面与当前流行的串口调试工具基本相同。该工具使用方便，而且可以自定义串口速率，由状态显示内容(serial debugging aids source, their preparation, interface with the popular serial debugging tools basically the same. The tool is easy to use, but can define serial rate, as indicated by the state)
