Developing Modem Applications

Here is a brief description of how such a scenario might work:

•The modem is idle.

•The host application sends a short SMS message to the modem from the Gateway, perhaps using an email account on the Internet. (A sample email address might be “mdn@msg.globalstarusa.com.” This is an example only. Contact your Service Provider to get the latest SMS message address format for your modem.)

•Your DTE application has set up the modem to listen for SMS messages, in one of two ways:

❑By turning SMS alerting on (using AT$QCSMSA).

❑By having the DTE application poll for messages with a timer (using the AT$QCSMSI command).

•When the modem gets an SMS alert, it notifies the DTE application.

•The DTE application queries the modem for the SMS message (using AT$QCSMSP and/or AT$QCSMSM).

•The DTE application parses the message, looking for strings that tell it to connect to the host application.

•The DTE originates a data call (packet or asynchronous).

Once the call has been established, the modem functions simply as a “pipe” for data between the host server and DTE applications.

Note

See the CD-ROM in your Modem Integrator’s Kit for a sample SMS

script. Also see SMS Commands on page 6-51.

 

Globalstar Service Alerts

Service alerts are sent on the Control port or queued (if only the Data port is connected and in use) whenever a service parameter changes:

•Fades — Gateway/satellite coverage is lost for any reason.
