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.
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.
