This section outlines the AT commands supported by the T630/T628. The information here can be of use for advanced users, to indicate the possibilities they have to:

On-line data mode

Allows “normal” operation of the built-in modem, for exchanging data or facsimiles with a remote modem.

• develop new communications software

add the T630/T628 to an application’s list of compatible modems

adjust the settings of their mobile telephone and modem

The modem in the T630/T628 supports the V.25ter command set, which is the standard communica- tion set used by modems.

The T630/T628 is compatible with industry de facto extensions, ETSI 07.05, 07.07 and 07.10.

Overview of AT command functions

AT commands are used to configure the mobile tel- ephone, to request information about the current configuration or operational status of the mobile phone, and to test availability and request the range of valid parameters, when applicable, for an AT command.

The built-in modem can be set to any one of three modes of operation. These are:

Off-line command mode

The command mode for entry of AT commands, when the device is first turned on.
