1 BEFORE YOU BEGIN
1.1 Features
These Fax/Data Modems combine the features of a 56000(receive only)/33600/28800/14400/9600 bps
data modem and a 14400/9600 bps FAX modem. Your new Fax/Data Modem gives your personal
computer the ability to send and receive FAX messages over the telephone line like a standard FAX
machine. Your Fax/Data Modem also allows your PC to communicate with other personal computers,
terminals or BBS's (Bulletin Board Systems) through the data modem functions.
When used as a data modem your Fax/Data Modem uses the standard AT command set and is fully
compatible with ITU-T V.42, V.42bis, V.34 (ANNEX 12), V.32bis, V.32, V.22bis, V.23, V.22, V.21,
MNP 2-5, Bell 103, 212A, V.90. When used as a Fax/Data Modem it communicates with all ITU-T
Group 3 FAX machines and is compatible with ITU-T V.27ter and V.29, V.17, T.4 and T.30.
Switching between DATA mode operation and FAX mode operation of your Fax/Data Modem is done
through its firmware, no hardware settings are required.
The communication software, which should be used, depends on the kind of machine that you are
going to communicate with. If you are going to call a FAX machine then you must use the Fax
software. If the machine that you are going to communicate with is a modem then you must use a data
modem communications software.
Note: This manual is written to be used for several models of Fax/Data Modems. Some of the
information in this manual may not apply to your fax/data modem.
All the description in this manual about Caller ID, V.90 and Fax class 1applies only to the
models which support these functions.

4. COMMAND REFERENCE
This chapter includes all commands, S-Registers supported by the modem. Before using the
commands, make sure your communications software package provides the function of operating the
modem through its interna1 commands. If your software does not support the function, ignore Chapter
4 and 5.
More than one command can be placed on a single line and, if desired, separated with spaces for
readability. Once the carriage return (Enter) key is pressed, the command line will be executed. A line
with no carriage return is ignored. If you come across terms that you don't understand, consult the
glossary. Words in boldface type are command names, commands, or default settings. Carriage returns
(Enter) are noted with <CR> or [ENTER]; this does not mean to enter these characters literally; but
instead to press the Enter key.
The modem accepts either upper or lower case characters in the command line and ignores any space
within or between commands. Typing errors can be corrected with the Backspace key. Exceptions are
noted in the description of specific commands.
Variables (r and x) are listed in italics. Punctuation symbols (, ; ! @) use as dial modifiers are listed
alphabetically according to their English names at the beginning of Section 4.2 Where two commands
are separated by a slash, either command will have the same effect. For example, if the command is
listed as B0/B, issuing either B0 or B will have the same effect.
Note: Except for the A/ command and the + + + escape command described in Section 4.3, all
commands must be prefixed with the attention code AT. For instance, the A command (below)
would be entered as: "AT A <CR>". Without the AT prefix, the command line cannot be
executed. Once entered, AT cannot be deleted with the Backspace or Delete keys.
4.1 AT Commands
4.1.1 Basic Command Set
A Go On-line in Answer Mode
This command instructs the modem to go off-hook immediately and then make a handshake
with the remote modem. Handshaking is not available during leased line operation.
Ais usually used to manually answer an incoming call or to switch from voice conversation to
data communication.
Bn Select Protocol to ITU-V.22 or Bell 212A
B0/BSelects ITU-V.22 protocol once the command line prefix AT has been entered at the
1200 bps data rate.
B1 Selects BELL 212A protocol once the command line prefix AT has been entered at the
1200 bps data rate. (Default)
D Go On-line in Originate Mode
D instructs the modem to go off-hook immediately and automatically dial the number
contained in the dial string following D. The dial string may contain any of the dial modifiers

contained in the following section. The D command without a dial string is usually used to
switch from voice conversation to data communication or to call a remote modem in leased-
line operation mode.
En Command Echo
E0/E Disables command echo.
E1 Enables command echo. (Default)
Hn Hang Up
H0/HGoes on-hook. (hangs up)
H1 Goes off-hook. (ready to dial)
In Identification
I0/IReport the product code.
I1 Report the hardware checksum.
I2 Report " NVRAM Test Result ".
I3 Report “TP560 Data/Fax/Voice 56K Modem).
I4 Report Firmware Version.
I5 Report the country code parameter.
I6 Report Local Phone Status.
Ln Control Speaker Volume
L0/LLow volume.
L1 Low volume.
L2 Medium volume. (Default)
L3 High volume.
Mn Monitor Speaker On/Off
M0/MSpeaker is always off.
M1 Speaker is off while receiving carrier. (Default)
M2 Speaker is always on.
M3 Speaker disabled while dialing.
Nn Automode Enable
N0/N Automode detection is disabled.
N1 Automode detection is enabled.(Default)
On Return to On-Line Data Mode

O0/O Enters on-line data mode without a retrain. Handling is determined by the Call
Establishment task. Generally, if a connection exists, this command connects the
DTE back to the remote modem after an escape (+++).(Default)
O1 Enters on-line data mode with a retrain before returning to on-line data mode.
O2 Enters on-line data mode with a rate re-negotiation before returning to on-line data
mode.
P Set Pulse Dial as Default
Causes the modem to assume that all subsequent dial commands are pulse dials. You may
omit the " P" from the dial strings.
Q Result Code Display
Determines whether the modem sends the result codes to the DTE.
Q0/QEnables result codes to the DTE (Default).
Q1 Disables result codes to the DTE.
T Set Tone Dial as Default
Causes the modem to assume that all subsequent dial commands are tone dial.
Vn Select Word or Digit Result Codes
V0/VDisplays result codes in digital format.
V1 Displays result codes in verbose format. (Default)
W Connect Message Control
This command controls the format of CONNECT messages.
W0/W Upon connection, the modem reports only the DCE speed (e.g., CONNECT 19200).
Subsequent responses are disabled.
W1 Upon connection, the modem reports the line speed, the error correction protocol,
and the DTE speed, respectively. Subsequent responses are disabled.
W2 Upon connection, the modem reports the DCE speed (e.g., CONNECT 14400).
Subsequent responses are enabled.(Default)
W3 Upon connection, the modem reports the line speed, the error correction protocol,
and the DTE speed, respectively. Subsequent responses are enable.
Xn Extended Result Codes
This command selects which subset of the result messages will be used by the modem to
inform the DTE of the results of commands.
Blind dialing is enabled or disabled by country parameters. If the user wishes to enforce dial
tone detection, a "W" can be placed in the dial string(see Dcommand). Note that the
information below is based upon the default implementation of the Xresults table.

If the modem is in facsimile mode (+FCLASS=1) , the only message sent to indicate a
connection is CONNECT without a speed indication.
X0/X CONNECT result code is given upon entering online data state. Dial tone and busy
detection are disable.
X1 CONNECT<text> result code is given upon entering online data state. Dial tone and
busy detection are disable.
X2 CONNECT<text> result code is given upon entering online data state. Dial tone
detection is enabled, and busy detection is disable.
X3 CONNECT<text> result code is given upon entering online data state. Dial tone
detection is disabled, and busy detection is enable.
X4 CONNECT<text> result code is given upon entering online data state. Dial tone and
busy detection are enable.(Default)
Z Reset
Zn, which must be placed at the end of the command line, resets the active configuration of the modem
to the stored configuration saved in nonvolatile RAM, hangs up the modem, and clears the command
buffer.
Z0/Z Resets the modem and loads stored configuration 0.
Z1 Resets the modem and loads stored configuration 1.

serial port.
&D0/&DDTR is ignored. Allows operation with DTEs that do not provide DTR.
&D1 DTR drop is interpreted by the modem as if the escape sequence has been entered.
The modem returns to the command state without disconnecting.
&D2 DTR drop causes the modem to hang up. Auto answer is inhibited. (Default)

flow. When the buffer is nearly empty, the modem will either send an XON or raise CTS to start the
data flow.
&K0/&K Disable DTE/DCE flow control.
