AT+CGAUTO
Automatic response to a network request for PDP context activation:
The test command returns the values of <n> supported by the MT as a
compound value.
The write command disables or enables an automatic positive response (auto-
answer) to the receipt of a Request PDP Context Activation message from the
network. It also provides control over the use of the V.250 basic commands
ATS0, ATA and ATH for handling network requests for PDP context activation.
=0 Disable automatic response for network requests for GPRS PDP context
activation. GPRS network requests are manually accepted or rejected by the
AT+CGANS command.
=1 Enable automatic response for network requests for GPRS PDP context
activation. GPRS requests are automatically accepted according to the
description below.
=3 Modem compatibility mode. The automatic acceptance of both GPRS and
incoming CSD calls is controlled by the ATS0 command. Manual control uses the
ATA and ATH commands, respectively, to accept or reject GPRS network
requests or incoming CSD calls.
AT+CGDATA
Enter data state:
The test command is used for requesting information on the supported layer 2
protocols to be used between the TE and MT.
The write command causes the MT to perform all actions which are necessary to
establish communication between the TE and the network using one or more
GPRS PDP types. This may include performing a GPRS attach and one or more
PDP context activations. Commands following the AT+CGDATA command in the
AT command line will not be processed by the MT.
=“PPP“ layer 2 protocol PPP supported
AT+CGDCONT
Define PDP Context:
The test command returns supported values as a compound value.
The read command returns the current settings for each defined PDP context.
The write command specifies the parameters for a PDP context identified by the
context identifier <cid>. The number of contexts that may be in a defined state
at the same time is given by the range returned by the test command. A special
form of the write command (AT+CGDCONT=<cid>) causes the values for
context <cid> to become undefined.
