Chapter 2 – Configuration
Commands
The AT commands described in this chapter allow the external application to determine the modem’s behavior under
various conditions.
2.1 AT&F Set All Current Parameters to Manufacturer
Defaults
Description: AT&F sets all current parameters to the manufacturer defined profile. All defined GPRS contexts
which are not activated or not online will be “undefined” if the non-volatile storage of the
+CGDCONT setting is not activated by the AT^SCFG parameter "GPRS/PersistentContext" (see
+CGDCONT).
Syntax: Exec Command: AT&F[<value>]
Response: OK
Parameter:
<value>
0 Sets all TA (terminal adapter) parameters to manufacturer defaults.
Notes:
• List of parameters reset to manufacturer default can be found in Section 20.6, Factory Default Settings
Restorable with AT&F.
• In addition to the default profile, you can store an individual one with AT&W. To alternate between the two
profiles enter either ATZ (loads user profile) or AT&F (restores factory profile).
• Every ongoing or incoming call will be terminated.
• This command is not PIN protected.
• This command is supported in airplane mode.
2.2 AT&V Display Current Configuration
Description: AT&V returns the current parameter setting. The configuration varies depending on whether or
not PIN authentication has been done.
Syntax: Exec Command: AT&V[<value>]
Response: Active Profile (See Section 2.2.1 AT&V responses)
OK
Parameter:
<value>:
0 Profile number
Notes:
• The value of \Q (flow control) is also determined by the AT+IFC command. In case the value set by AT+IFC
cannot be represented by a \Q equivalent, \Q255 will be displayed.
• The parameters of AT^SMGO can only be displayed after the SMS data from the SIM have been read
successfully for the first time. Reading starts after successful SIM authentication has been performed, and
may take up to 30 seconds depending on the SIM used. While the read process is in progress, an attempt to
read the parameter will result in empty values.
• The parameter of AT+CSDH will only be displayed in SMS text mode, see AT+CMGF.
• This command is not PIN protected.
• This command is supported in airplane mode.
