AT command
AT commands are commands for setting the FOMA
terminal functions from a PC.
FOMA terminals comply with AT commands and
support some extended commands and proprietary AT
commands.
About the AT command
■ AT command input format
“AT” must be entered before each AT command.
Commands must be entered in one-byte
alphanumeric characters. An input example is as
follows:
AT commands and their parameters (numbers or
symbols) must be entered on a single line. Enter all
the characters from the first character to the
character just before
in a single line. Up to 160
characters (including “AT”) can be entered in each
line.
■ AT command input mode
To operate the FOMA terminal using AT commands,
the PC must be in the terminal mode.
Terminal mode is a mode that lets the PC operate
as a single communication terminal. Characters
entered from the keyboard are sent to the device or
line connected to the communication port.
･
Offline mode
The FOMA terminal in standby status. Usually, the
FOMA terminal must be in this status to use AT
commands to control it.
･
Online data mode
The FOMA terminal is in the communication
mode. If you enter AT commands when the FOMA
terminal is performing communication, the
received characters are sent directly to the
communication receiver and may cause the
receiver’s modem to malfunction. Do not enter AT
commands while the FOMA terminal is performing
communication.
･
Online command mode
AT commands allow you to operate the FOMA
terminal even when the FOMA terminal is in the
communication mode. This mode makes it
possible to execute AT commands without
interfering with the connection to the
communication receiver, and normal
communication can be continued after the
commands have finished executing.
INFORMATION
●
In case of executing 64K data communication or
videophone call via external connection devices, a call is
made with Number A when 2in1 is in the A mode or dual
mode. In the B mode, a call is made with Number B.
Switching between the online data mode and
online command mode
To switch the FOMA terminal from the online data
mode to online command mode, you can use either of
the following procedures:
･
Enter the “
+++
” command or the code set in the “S2”
register.
･
Turn the RS-232C*
1
ER signal off when set in
“AT&D1”.
To switch from the online command mode to the online
data mode, enter “ATO ”.
*1 The USB interface emulates an RS-232C signal line,
so RS-232C signal control using communication
applications is possible.
