[Introduction]： Designed for the communication between UART and net server via GPRS, it is with easy AT setting and dual transparent transmission available.It explains how to make the simplest hardware environment and test the transparent transmission. The transparent transmission is between UART devices（referring to PC） and net sever (replaced by TCP testing tools).
