AT commands support
This section outlines the AT commands supported
by the Z600. The information here can be of use for
advanced users, to indicate the possibilities they
have to:
• develop new communications software
• add the Z600 to an application’s list of compati-
ble modems
• adjust the settings of their mobile telephone and
modem
The modem in the Z600 supports the V.25ter com-
mand set, which is the standard communication
set used by modems.
The Z600 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.
On-line data mode
Allows “normal” operation of the built-in modem,
for exchanging data or facsimiles with a remote
modem.
On-line command mode
For sending AT commands to the built-in modem
while remaining connected to a remote modem.

• Control and Identification
