Note: No automatic answer
•
•
Automatic dialing of the phone number stored in the first location of the ADN phonebook, (or
FDN phonebook, if it is activated using the +CLCK command).
Automatic sending of the short message (SMS) stored in the first location of the SIM.
The number of rings before an automatic answer (3 characters padded with zeros)
Range of values is 0 to 255.
Enables or disables automatic message transmission or number dialing. Informs the
product that the number is a voice number rather than a data number.
Disables automatic DTR number dialing / message transmission.
Enables automatic DTR dialing if DTR switches from OFF to ON. Dials the phone number
in the first location of the ADN phonebook (or FDN phonebook, if it is activated using the
+CLCK command). Voice call with semicolon.
Activates automatic DTR dialing if DTR switches from OFF to ON. Dials the phone
number in the first location of the ADN phonebook (or FDN phonebook, if it is activated
using the +CLCK command). Data call without semicolon.
Activates automatic DTR message transmission if DTR switches from OFF to ON. Sends
the short message in the first location of the SIM.
Note: If the first location is empty:
