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
Always enter an AT command by adding AT at the
beginning of the command. Be sure to use half-width
alphanumeric characters. An input example is given
below.

Parameter: Description of the command
Command: Command name
Always enter an AT command including a parameter
(number and symbol) right after the command in one
line. One line means the row of characters from the first
character to the character immediately before pressing
# .

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 com-
munications terminal. The characters entered from the
keyboard are sent to the line and equipment connected
to the communications port.
● 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 communications 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 communications.
● Online command mode
This mode allows you to operate the FOMA terminal using AT
commands even if it is in the status where communications is
in progress. In this case, an AT command is executed while
the terminal remains connected to the destination. You can
continue communications again after completion of the AT
command execution.
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
# ”.
