这是一个用于油田电表抄表的程序；能够发送手机短信，使用SQLSERVER数据库储存数据；使用pcomm通讯控件控制无线调制解调器，调用AT指令集。正在现场运行，极有应用价值。-This is a meter used for oil field meter reading procedures capable of delivering a phone message, using a database storing data SQLSERVER PComm communications control to control the use of wireless modems, call the AT instruction set. Were at the scene running, there is a strong application value.

modbus应用的典型例子，从设备slave应用程序，希望初学者看一看-a typical example of the application of modbus, slave application from the device, hoping to see beginners

发送UDP的源代码-send UDP source code

这是一个串口监视程序，每个串口接一个设备，通过监视串口可以判断设备是否正常运行。串口是通过外接的串口卡接出来的！-This is a serial port monitoring program, each serial port after another device, by monitoring the serial port can determine whether the normal operation of equipment. Serial port through an external serial port card out then!

好东东，虚拟串口驱动程序，里面含有相关 串口监视界面。-good Dongdong, virtual serial port driver, it contains relevant surveillance serial interface.

端口专家是一个优秀的端口（串口、并口）监视、调试程序，有以下基本功能： 1.能动态设置各种通讯速率、奇偶校验、数据位、停止位和流控； 2.可以16进制形式自动显示接收到的数据，并能同时发送ASCII码（包括中文）和16进制字符串，可以任意设定自动发送周期,定时发送数据； 3.能将接收数据保存成文本文件,便于比较观察；并能发送任意大小的数据文件（以二进制形式发送）； 4.能自动保存设置参数，无需每次重新设置。-port experts is a good ports (serial, parallel) monitoring, debugging procedures, the following basic functions : 1. Dynamically created various communications rate, parity, data bits, stop-and flow control; 2. May 16-band automatic form of data received and at the same time sending ASCII (including Chinese) and 16 string band can be set to automatically send arbitrary cycle, regularly send data; 3. preservation can receive data into text files, facilitate comparison of observation; and the ability to send any size of paper (in binary form Send); 4. Save the settings automatically parameters, each without re-instated.

本文主要阐述了DTMF的原理及如何在MATLAB上产生DTMF信号，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程，完成对电话拨号音系统的简单的实验仿真。-This paper described the principle and how DTMF in MATLAB to generate DTMF signals, mainly related to the telephone dial tone of the basic principles of synthesis and identification of the main methods, the use of MATLAB software and the FFT algorithm on the telephone communication system dial tone Synthesis and Recognition . And further the use of MATLAB in the production of graphical user interface simple and intuitive GUI interface simulation. Able to take advantage of matrix synthesis of different fundamental frequency 0- 9 different keys of the dial tone and be able to different dial tone to be the correct identification, the dial tone from a telephone number to resolve the process of completion of the telephone dial tone system, a simple experiment simulation
