用于通信模块的短消息类的设计与实现

DESIGN AND IMPLEMENTATION OF TEXT MESSAGE CLASS USED FOR COMMUNICATION MODULE

介绍短消息发送实体、短消息协议数据单元与AT指令集。在VC6.0基础上,编写通信模块短消息类,通过串口发送AT指令与通信模块通信,实现短消息的设置、收发等功能,出口参数具有错误和状态提示,方便用户进行再开发。该短消息类已在SIE-MENS公司MC75模块上调试成功。

This paper briefly introduces the sending entity and protocol data unit of text message as well as AT command set. Based onVC6.0 the text message class for communication module is compiled, and the AT command is issued via serial interface to correspond with the communication module, so as to realise such functions of setting up the text messages, sending and receiving these messages, etc. , the output parameter provides the indication of error and status of the module to facilitate the re-development by users. The text message class has been successfully debugged on MC75 module of SIEMENS.
