GSM模块AT命令组装和AT命令响应解析程序。实现了自动组装标准AT命令并发送到GSM模块，同时可以提取GSM模块输出的所有AT命令，同时实现了大量AT命令响应的解析工作。主要的过程采用了Contiki的进程模型。-Making and parsing routine for AT commands of GSM module. It can automatically make standard AT commands and sent it to GSM module, while it can get all the AT commands sending　GSM module, and analysis a　large number of AT command responses. The main process uses a process model of Contiki.
