Developing Modem Applications

Mobile-Originated Packet Data Calls

The GSP-1620 modem lets the application device (DTE) connected to the modem originate a packet data call.

Steps TO MAKE A MOBILE-ORIGINATED PACKET DATA CALL

■Use the ATD#777 command.

The modem returns CONNECT if the call has been established (for other result codes, see Dial (D) on page 6-20).

For another example, see Making a Call from the Data Port on page 4-4.

Steps TO HANG UP A PACKET DATA CALL

1.Enter Online-Command mode by using the in-band control data escape sequence, “+++” surrounded by guard time (for details, see Change from Online to Online-Command Mode (+++) on page 6-40).

2.Use the ATH command (to hang up and end dormant mode).

or

Use the ATH777 command (to hang up but leave dormant mode active).

Mobile-Terminated Packet Data Calls

The GSP-1620 modem lets the application device (DTE) connected to the modem receive a packet data call. It is the responsibility of the DTE application to keep the modem powered up if it is to receive incoming packet data calls.

However, the first Gateway software release that supports GSP-1620 modems does not support over-the-air mobile-terminated calls. Future releases of the Gateway software will support mobile-terminated calls to fixed IP addresses, and no modem upgrades will be required.
