※
Returns OK if only AT is entered.
AT
o
OK
AT%V
Displays FOMA terminal
version.
*2

Ver1.00
OK
AT&C<n>
Sets operating condition for circuit
CD (DCD) signals sent to DTE.
*1
n=0 : Circuit CD always ON
n=1 : Circuit CD signal changes according to
line connection status (default setting)
When “&C1” is set, the CD signal is turned
“ON” directly before the CONNECT signal is
sent when connection is completed. The CD
signal is turned “OFF” right before “NO
CARRIER” is sent when the circuit is
disconnected.
AT&C1
o
OK
AT&D<n>
Sets the operation when the
circuit ER (DTR) signal received
from DTE changes from “ON” to
“OFF” during online data mode.
*1
n=0 : Ignores status (always considers signal
ON)
n=1 : Sets online command mode when
signal changes from ON to OFF
n=2 : Disconnects line and activates offline
mode when signal changes from ON to
OFF (default setting)
AT&D1
o
OK
AT&E<n>
Selects speed display
specifications when connecting.
*1
n=0 : Wireless area transmission speed
appears.
n=1 : DTE serial transmission speed appears.
(Default setting)
AT&E0
o
OK
AT&F<n>
Resets the FOMA terminal’s AT
command settings to their default
settings. If this command is entered
during communication, the settings
are reset after disconnected.
*2
Can only be set as n=0 (can be omitted).
AT&F
o
OK
AT&S<n>
Controls when the signal of data
set ready (DR) is set to DTE.
*1
n=0 : Always ON (default setting)
n=1 : DR signal ON when line is connected
AT&S0
o
OK
AT&W<n>
Stores the current settings in the
FOMA terminal’s memory.
*2, 5
Can only be set as n=0 (can be omitted).

DANTE
Displays number of antennas on
TE.
*2
The result from this command is in the
following format.
*
DANTE:<m>
<m>
0: Status where outside the service area
appears on the FOMA terminal
1: Status where zero or one antenna
appears on the FOMA terminal
2: Status where two antennas appears on
the FOMA terminal
3: Status where three antennas appears on
the FOMA terminal

DGANSM=
<n>
Sets Accept/Reject call modes for
incoming packet communications.
This setting is only valid for
incoming packet communications
after entering setup commands.
*2
n=0 : Sets Reject call and Accept call settings
to
OFF
(Default setting)
n=1 : Sets Reject call settings to
ON
n=2 : Sets Accept call settings to
ON

DGAPL=<n>
[,<cid>]
Sets host (APN) to accept
transmissions for incoming packet
communications. APN settings
use <cid> parameter defined by
“+CGDCONT”.
*2
Adds or deletes from Accept calls list with <n>
parameter. If <cid> parameter is abbreviated,
adds (<n>=0) or deletes (<n>=1) all of <cid> to
list. Adds (deletes) <cid> not defined with
“+CGDCONT” to list with this command.
n=0: Adds to list (Adds APN defined by <cid>
to Accept calls list.)
n=1: Deletes from list (Deletes APN defined by
<cid> from Accept calls list.)
