<passwd>: string type, enclosed by “ “; for example, “1234”.
Note:
Factory default SIM card PIN Code is “1111”
Note:
Factory default Phone Unlock Code is “1234”
<classx> is a sum of integers each representing a class of information:
1
voice
2
data
4
fax
This parameter defaults to 7, equal to all classes, but the A3LA-RS only supports Voice Call
Barring so this is illegal. Therefore in practice the DTE must supply <classx>=1 when
querying or changing the status of any Call Barring facility. When querying (<mode>=2),
<passwd> is irrelevant and should be supplied as ”” in order to allow the <classx>=1
parameter to be supplied.
For facilities “CS”, “SC”and “FD”, the <passwd> and <classx> parameters are not relevant
and will be ignored if supplied.
Test Command:
+CLCK=?
Test command returns the facility values supported by the phone. The response is in the form:
+CLCK:(list of supported <fac>s)
Note:
Only “CS” will appear as a supported value if there is no SIM card in the device.
Note:
+CLCK is closely related to +CPIN and +CPWD. See these commands for additional
information.
A.8.118 +CPWD – Change Password
Exec Command:
+CPWD=<fac>,<oldpwd>,<newpwd>
This command sets a new password for the facility lock function defined by the AT command
Facility Lock +CLCK. The following parameter values are currently supported:
<fac>:
“CS”
CNTRL Surface (Phone Unlock Code)
“SC”
SIM (SIM Card PIN Code)
“P2”
SIM PIN2 (SIM Card PIN2 Code)
“AB”
Call Barring password (single password used for all call barring supplementary
services)
Note:
AT+CPWD=”SC”,<oldpwd>,<newpwd> will return “Error” unless the SIM Card Pin Code
is currently activated (see AT command Facility Lock +CLCK).
Note:
A user interface may prompt the user for two copies of the new password, in which case
it should check the two are identical as only one copy is needed for this command.
