AT commands are commands used to set the
FOMA terminal functions from a PC. When AT
commands are entered from a PC, the FOMA
terminal performs the corresponding operations.
J
AT command input format
AT commands must always start with “AT”. Enter
in single-byte alphanumeric characters. Below is
an input example.
Each AT command including parameter (number
or symbol) following the command must be
entered on a single line. A single line means the
characters from the first character until the
character directly before the
o
is pressed. Up to
160 characters (including “AT”) can be entered.
J
AT command input modes
To operate the FOMA terminal using AT
commands, set the PC to terminal mode. In
terminal mode, the characters entered from the
keyboard are sent directly to the communication
port to operate the FOMA terminal.
Offline mode
The FOMA terminal is in stand-by. Normally, this
mode is used to operate the FOMA terminal using AT
commands.
Online data mode
The FOMA terminal is connected and performing data
communication. When an AT command is entered in
this mode, the characters are sent directly to the
receiver, and may cause the receiver’s modem to
malfunction. Do not enter AT commands in this mode.
Online command mode
Even when the FOMA terminal is connected and
performing communication, with special operations,
operation by AT commands is possible. When in this
mode, AT commands are executed while remaining
connected to the receiver, and communications can be
resumed after the operation is completed.
J
Switching between online data mode
and online command mode
Use either of the following methods to switch the
FOMA terminal from online data mode to online
command mode.
Enter “+++” command, or enter the set code in the
“S2” register.
Turn the RS-232C* ER signal OFF when set to
“AT&D1”.
To switch from online command mode to online
data mode, enter “ATO
o
”.
* USB interface emulates an RS-232C signal line,
enabling RS-232C signal line control by the
communication application.
