本文介绍了短信的原理和实现方法，重点说明了短信的编码方式、AT指令以及用C#实现串口通讯的方法-This article describes the principle and implementation of SMS, text messages highlighted the encoding, AT commands and serial communication with the C# method to achieve

短信的发送需要GSM模块和处理器协作完成,GSM模块与ARM处理器通过串口连接,处理器向串口发送接收AT命令与 GSM模块形成通信回路。-Send text messages GSM modules and processors need to be completed in collaboration, GSM module and the ARM processor through the serial port connection, the processor to the seri

这是本人的一个正式项目中所做的测试工程源码。主要功能是通过串口与板子的GSM模块进行通讯，进行收发短信的程序。内容有：串口设置，GB2312与UNICODE编码转换，PDU编解码（此部分大部分借鉴了网友的代码）,AT指令发送。完全可以将相关代码移植到嵌入式短信收发设备中去。我的相关嵌入式项目也确实是在这个基础上做的。-This is my project done by a formal evaluation of the source. Main functions of the board

api串口通信，采用win32API用C++BUILDER实现的串口通信，可实现与一般通信设备的AT命令交互-api serial communication，C + + BUILDER win32API with implementation of the serial communications, AT commands to interact with the general communications equipment
