Introduction of GSM Modem?RS232/RS485

Industrial Serial to IP cellular GPRS modem which convert the serial data RS232/485 into IP data and then transfer to data center through GPRS 2.5G mobile network. USR-GPRS232-730?is based on USR-GM3.?Can use this product to realize bidirectional transparent transmission from serial port to network through simple AT command.
