Specifications of GSM/GPRS Terminal : The Virtual iM2M terminal (GSM/GPRS Modem IPR paid with valid IMEI) is a general purpose intelligent device for various remote monitoring applications. This evice can be used for different applications and the embedded software loaded to this device determines the usage of the device. Features of embedded Software :

• A GSM/GPRS enabled SIM is supposed to be installed in the Terminal. Based on the Operator, the GPRS settings have to be configured in the terminal.
• Once a proper SIM card is inserted and the terminal is switched ON, it will register to the GSM/GPRS network using public APN.
• The terminal will continuously monitor RS-232 port for messages received from the device connected.
• When modem receives a valid command in the RS-232 port it will take appropriate action based on the commands. (Send SMS/Send Email/Send HTTP/Provide Network Status)
• Whenever the modem receives any SMS, it will be pushed through RS-232 port.
• Stores Failed GPRS packets in non-volatile memory until system re-stores proper GPRS connection to server (zero data loss).
