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” (see AT+CGDCONT).
Exec Command Syntax: AT&F[value]
Response: OK
Parameter Description:
<value>
0 Sets all TA 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.
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 and whether or not Multiplex mode is
enabled (see AT+CMUX).
Exec Command Syntax: AT&V[value]
Response: Active Profile (See Section 2.2.1 AT&V responses)
OK
Parameter Description:
<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.
