A real-time wireless remoting monitor terminal is designed based on the ARM platform and embedded Linux OS with mature GPRS/GSM technology. The MC39i module for AT commands protocol and protocol data unit (PDU) for encoding and decoding process are discussed in detail

the implementation method between MC39i module and terminal device is provided under Linux.The GUI will greatly improve the efficiency of human-device interaction

then this paper focuses on how to establish the development environment of QT/Embedded and how to porting an application to mobile terminal. The effect is proved to be well in practice.
