Using the Pocket GSM as a GSM modem
The Pocket GSM has a 9 pin D type connector for standard RS232 serial communications.
It operates using the standard 'AT' command set. In order to get full functionality out of the serial port then the Input/Output functionality of the Pocket GSM has to be disabled by issuing the commands AT+WOPEN=0 followed by the save command (AT&W).
The Pocket GSM can interface a wide range of Baud rates, with different handshaking modes and can be set to automatically answer etc.. You can use the Pocket GSM connected to a programmable logic controller (PLC) to allow remote programming functionality, or you could connect to an existing data logger for remote data acquisition.
