Enfora Enabler II-G Assisted GPS
Modem Integration Guide
9.4. Selecting the GSM Modes of Operation
When provisioning the SIM for the Enfora Enabler II-G A-GPS module, enable the following modes of
operation:
• Voice calls: configure the SIM for both MO and MT service (to send and receive)
• SMS: configure the SIM either for MT alone (to receive) or for both MO and MT (to send and
receive)
• Circuit Switched Data: configure the SIM either for MO alone (to send) or for both MO and MT (to
send and receive)

10. Software Interface
10.1. Software Interface
The application sends commands to the Enfora Enabler II-G A-GPS module via the 60-pin I/O signal
connector. These commands use the Enfora AT Command Set and/or Enfora’s Packet API.
The Enfora Enabler II-G A-GPS module operates in one of the following modes:
• Command mode: Used for configuring the Enfora Enabler II-G A-GPS module, for interrogating
the GSM network, and for placing and receiving calls. It uses the AT command set via the serial
port for communication.
• On-line mode: Used after a circuit-switched data call has been established. Data is passed
between the Enfora Enabler II-G A-GPS module and the controlling application without command
interpretation. The only AT command that is interpreted in On-line mode is the +++ command.
(This command places the Enfora Enabler II-G A-GPS module in Command mode but does not
terminate the circuit-switched data call.)
• IP Packet /API Mode: Used to read/write modem parameters, interrogate network information,
and place and receive calls in real-time, multi-tasking mode. The Packet API mode is facilitated
over a PPP connection and the packets can be constructed according to the information provided
in the Enfora GSM-GPRS Family UDP-API Reference GSM0102PB002MAN. Enfora GSM-
GPRS Family Modem Control Library Reference GSM0000PB006MAN provides detail of the
UDP Modem Control Library that has three levels: port, messaging, and modem libraries. Each
of the three levels contains one or more libraries. For example, the port libraries layer has UDP
PPP Port, UDP Socket Port, and COM Port libraries. All libraries are provided as a part of the
Enfora Enabler II-G Assisted GPS Module Integration Toolkit.
• GPS only mode: Used for configuring the Enfora Enabler II-G A-GPS module, for interrogating
the GPS satellite network and sending NMEA data. It uses the AT command set via the serial
port for communication.
