AT+CGCMOD PDP context modify
Extension of ATD – Request GPRS service
Description: Modifies the specified PDP context(s) with respect to QoS profiles and
TFTs. After the command has completed, the MT returns to V.25ter online
data state.
If no <cid>s are specified the activation form of the command modifies all
active contexts.
Execution
command: AT+CGCMOD=[<cid>[,<cid>[,…]]]
Test command: AT+CGCMOD=? Shows if the command is supported.
Test command
response: +CGCMOD: (list of <cid>s associated with active contexts)
Parameter:
<cid>: See the AT+CGDCONT command.
Description: The V.25ter ATD command causes the MT to enter the V.25ter online data
state and, with the TE, to start the specified layer 2 protocol. The MT
returns CONNECT to confirm acceptance of the command prior to enter-
ing the V.25ter online data state. No further commands may follow on the
AT command line.
When the layer 2 protocol has terminated, either as a result of an orderly
shut down of the PDP or an error, the MT enters V.25ter command state
and returns the NO CARRIER final result code.
<L2P> and <cid> usage are the same as in the +CGDATA command. The
+CGDCONT, +CGQREQ, and so on, commands may be used in the
modem initialisation AT command string to set values for PDP type, APN,
QoS, and so on.
This command may be used in both normal and modem compatibility
modes.
Note: The dial string conforms to the syntax specified in GSM 02.30.
Execution
command: ATD*<GPRS_SC>[*[<called_address>][*[<L2p>][*[<cid>]]]]#
Parameters:
<GPRS_SC>: Digit string. A digit string (value=’99’) which identifies a request to use the
GPRS/Packet Domain.
<called_address>: String. Identifies the called party in the address space applicable to the
PDP.
<L2p>:
<L2p> Description
1 PPP
9yyyy M-xxxx
<cid>: Digit string. Specifies a particular PDP context definition.
