A/
Reissue last AT command
Re-executes the last command string entered. The last-executed command
remains in the command buffer until
AT
is entered again or the modem is reset
or power-cycled.
A/
will reissue that same command. It executes immediately
when the slash (
/
) is entered.
Note: This command is
not
preceded by
AT
and does not require
<CR>
to
terminate.
A
Answer incoming call (or GPRS network request)
GSM mode
When operating in
GSM voice, or CSD mode,
ATA
instructs the
modem to immediately go off-hook and attempt to establish a connection
without waiting for a ring. This is used to answer an incoming call if the auto-
answer status register (S0—see page 25) is disabled.
The command presumes a
RING
has been received. If the command is issued
without a
RING
, and the modem is in
command state,
the modem replies with
OK
and remains in command state.
Once the
RING
arrives, the modem looks for carrier to negotiate the connection,
and either issues:
•
CONNECT
and enters data state; or
•
NO CARRIER
and remains in command state.
GPRS mode
When operating in
GPRS packet mode,
the
ATA
command
answers a network request for a PDP context activation announced by the
unsolicited result code
RING
. The modem responds with
CONNECT
and enters
the V.25
ter
online data state to initiate a GPRS connection.
D**##[n]
Make GPRS connection
Establishes a connection using the specified profile. The
!MPSETUP
is used to
maintain profiles; up to three profiles are supported. (See page 56.)
The GPRS profile used in the connection is specified by
n
:
•
<n>=0
Default profile. (Set by the
!MPSETDFLT
command.)
•
<n>=1
Profile 1
•
<n>=2
Profile 2
•
<n>=3
Profile 3
The connection uses the PDP context settings assigned using
+CGDCONT
,
+CGQMIN
, and
+CGQREQ
to the PDP Context Identifier 1. (That is, the <cid>
must be 1.
D**##
cannot be configured to use any other value for the <cid>.) In
order to establish a connection with specific QoS (Quality of Service) settings,
or header or data compression settings, the settings must be assigned to PDP
Context Identifier 1 (<cid>=1) using the
+CGDCONT
,
+CGQMIN
, and
+CGQREQ
commands.
