4 MAKING SIMPLE DATA CALLS

This chapter is essentially a quick tutorial that demonstrates making simple packet data calls from the QUALCOMM Globalstar GSP-1620 Satellite Data Modem, including the following topics:

• Checking modem status

• Making simple packet data calls

❑ Making a call from the Data port ❑ Entering Online-Command mode

This chapter assumes that you have connected your modem as described in Chapter 2 and configured necessary service programming parameters as described in Chapter 3.

In addition, examples in this chapter assume you have a Windows PC connected to the modem, where Windows deals with the TCP/IP and PPP protocols. When you develop embedded SCADA applications, you can use off-the-shelf protocol stacks or write your own.

Note For more detailed information about making packet data calls, see Using Packet Data on page 5-21. For information about making asynchronous data calls, see Using Asynchronous Data on page 5-30.

Checking Modem Status

As you test a GSP-1620 modem and develop applications for it, you will often find it helpful to check the modem’s status.

The AT$QCSTATUS command provides important information about the modem, including whether it can “see” the Globalstar Gateway, how strong the Globalstar signal is,
