目前的智能机在硬件上多采用双cpu的架构，一个是基带处理器，主要处理数字信号、语音信号的编码解码以及GSM通信协议，另一个是应用处理器，运行操作系统和各种应用程序。基带处理器、射频和其它外围芯片作为一个模块，成为GSM/GPRS modem，提供AT命令接口。网络的应用已经是一个需求的热点，而目前的GSM模块大多都能支持GPRS功能。应用处理器通过AT命令集与带GPRS功能的无线通讯模块通信，为实现网络的应用提供了一个最底层的支持。 -Intelligent machines in the current hardware on many dual-cpu architecture of a baseband processor are mainly deal with digital signals, voice signals, and GSM codecs communication protocol, and the other is the application processor, operating system and applications running procedures. Baseband processor, radio frequency and other peripheral chips, as a module, as a GSM/GPRS modem, provided by AT command interface. Application of network needs is a hot spot, and most of the current GSM module can support GPRS function. Application processor through the AT command set and functionality with GPRS wireless communication module, in order to achieve the application of the network provides a bottom support.

vs2005开发环境下面用C#编写的虚拟RFID串口模拟器。当接从串口收到一个数据的时候，工具自动回复一个你定制的报文串。前提是需要有虚拟串口。也可以手动向串口发送报文的功能。-vs2005 development environment written in C# using the following virtual RFID serial simulator. Upon receiving a data received from the serial port when the tool automatically go back to a string of your custom message. The premise that the need for a virtual serial port. You can also manually send a message to the serial port function.
