AT Commands

AT commands are the commands (instructions) for
setting and changing the functions of the FOMA
terminal on a PC.
■ Input format of AT commands

beginning of the command. Be sure to use half-width
alphanumeric characters. An input example is given
below.

commands.
■ Input mode of AT commands
To operate the FOMA terminal using AT commands, set
the PC to the terminal mode.
The terminal mode is used for operating a PC as a
communication terminal. The characters entered from
the keyboard are sent to the device connected to the
communication port or the line.
● Offline mode
The FOMA terminal is in stand-by status. This mode is
normally used when you operate the FOMA terminal using AT
commands.
● Online data mode
The FOMA terminal is in the status where communication is
in progress. If you enter an AT command in this status, the
characters sent are sent to the destination in their original
form and the modem at the destination may develop a
trouble. Do not enter AT commands during communication.
● Online command mode
This mode allows you to operate the FOMA terminal using AT
commands even if it is in the status where communication is
in progress. In this case, an AT command is executed while
the terminal remains connected to the destination. You can
continue communication again after completion of the AT
command execution.
 When placing a voice/videophone call or originating 64K data
communication from an external device, if 2in1 is set to the
A mode or Dual mode, it is done by Number A. When the B
mode is set, it is done by Number B.
Switching between the Online Data
Mode and Online Command Mode
You can use the following two methods to switch the
FOMA terminal between the online data mode and
online command mode.
 Enter the code set to "+++" command or "S2" register.
 Set the ER signal of RS-232C(※) to OFF when "AT&D1" is set.
※ Since the RS-232C signal line is emulated by a USB
interface, RS-232C signal line control by the communication
application is enabled.
To switch from the online command mode to the online
data mode, enter "ATO ".
