3 - AT Commands, S-Registers and Result Codes
Chapter 3 - AT Commands, S-Registers
and Result Codes
Introduction
This chapter describes how to use MT3400ZLX AT
commands, S-Registers and Result Codes.
How To Use AT Commands
Usually, your fax and data comm software controls
the modem for you. However, you may also want to
use the AT commands. These commands give you
complete control over your modem. You need to be
careful when using these commands, because they
can cause your software to loose its ability to control
the modem. If you do find that an AT command has
caused a problem, then turn the computer off and
then back on. That will reset most AT commands to
the factory default settings. You can also type
AT&F&WZ
to go back to the factory default setting.
To use an AT command, you must first:
1. Run your communication software.
2. Configure the software for the appropriate COM
port and
IRQ settings, if necessary.
3. Enter Terminal mode (also i.e., “Command
mode”, “Local mode”, or “Direct mode”). This is
the mode in which most data comm software
packages start up. You can then type the
desired AT command, then press the Enter key.
16
MT3400ZLX Owner’s Manual
For example, type:
ATH0<Enter> to hang up the modem
connection, or
AT&K3<Enter> to enable bi-directional CTS/
RTS hardware flow control.
Most of the AT commands can be entered in
“strings” (i.e., on the same command line) without
spaces between the individual commands. For
example:
AT&K3H0<Enter>
As shown above, it is not necessary to put spaces
between the commands. So, there are no spaces
between AT,
&K3
, and H0.
The modem usually returns a response (or “Result
Code”) at the next line if it understands the
command. The response is usually
OK
or
ERROR
unless the AT command provides other (extended)
messages.
Basic A T Commands
Command OptionsFunction & Description
A/ Re-execute the last command string
<any key> Terminate the current connection
attempt when entered in handshaking
state
All the following commands require an “AT” prefix
A Go off-hook and attempt to establish a
connection without waiting for a ring
Bn Line modulation options
B0 Select ITU-T V.22 mode for 1200 bps
connection and V.21mode for 300 bps

P Pulse dial. Only digits 0 to 9 can be
dialed
R Reverse dial. Originate call in answer

waits for the second dial tone before
processing the dial string
, Pause. Cause the modem to pause for
a time before processing the dial
string (designed by S8 register)
! Flash hook (for call transfer). Cause
the modem to go on-hook for 0.5
second then return off-hook
@ Wait for 5 seconds of silence after
