INTRODUCTION
This manual tells you how to use the SFM 56.0-modem. For information about the use of
the fax and voice options, your should refer to the fax and voice software manuals.
The modem links two remote computers via a telephone line. One computer can then
receive data from or send data to the other computer. The modem can also be used to
connect with an external database, on the Internet for example. To use the Internet you will
have to subscribe to an Internet Service Provider (ISP).
About this manual
After the introduction in chapter one, chapter two describes the components, the
installation and connection of the Tornado SFM 56.0. In chapter three you will find an
explanation of the modem commands, followed in chapter four by the S-registers.
The appendices contain background information on a number of aspects, such as the
technical specifications of the modem and an ASCII-table. Finally there is an index to
make it easy for you to find subjects in the manual.
We hope you enjoy using your Tornado SFM 56.0!

The equipment has been approved according to resolution 98/482/EC for European single
terminal connection to the publictelephone network (PSTN). Because of minor differences
between the PSTNs in different countries, this approval does not it itself guarantee a
correct link with every PSTN connection point.
If you have any problems you should first contact your supplier.
TAKE NOTE: The manufacturer should ensure that the retailer and user of the
equipment are aware of the above.

1 CONNECTING THE MODEM
To install the Tornado SFM56.0 in a Windows 95/98 or Windows NT environment you
should consult the 'Brief User’s Guide'
1.1 Description of the Tornado SFM 56.0
On the front of the modem are a number of LED indicators showing the modem status.
From left to right these are:
Auto Answer (AA) , Carrier detect (CD), Offhook (OH), Received Data (RxD),
Transmit Data (TxD), DTR signal (DTR) and Power (PWR).
Figure 1.
Front of Tornado SFM 56.0
AA When the LED indicator AA is illuminated continuously, the modem is in
Auto-Answer mode. This means that the modem will connect as soon as
a call signal is detected. The indicator AA will flash as long as there is a
telephone connection.
CD The LED indicator CD indicates whether there is a connection with
another modem.

2 MODEM COMMANDS
This chapter describes the AT commands used for setting up and operating the Tornado
SFM 56.0.
2.1 Using the AT commands
Most modems and communications software uses the AT command set. Some modem
manufacturers add their own commands to the AT command set. Consequently there is no
longer one standard. A distinction is made between the 'Standard AT' and 'Extended AT'
command sets. If you are using Windows 95/98, it is generally not important to know the
AT commands.
2.2 Command line format
A command line begins with the letters AT, from the English word ATtention. The letters AT
should both be in either upper case or lower case. The command line ends with
<ENTER>. One ormore commands can be given on each command line. A command line
may not contain more than 54 characters. You cannot type more than 54 characters on
one line.
TAKE NOTE: The modem remembers the last command line. To repeat it, type: A/
(without <ENTER>).
For clarity commands must be separated from each other by spaces. The spaces count
towards the total length of the command line.
A command is sometimes followed by a parameter (number). If the parameter is 0, it may
be omitted. For example: ATE0 is the same as ATE.
From the letters AT at the beginning of the command line the modem identifies the baud
rate and parity of the terminal and configures itself accordingly. The rates which are
recognised automatically are 300, 1200, 2400, 4800, 9600, 19,200, 38,400, 57,600 and
115,200 bps.

TORNADO SFM 56.0

The modem can recognise data formats with 7-bit or 8-bit characters, with even, odd or no
parity bit and with one stopbit.
2.3 Overview of the AT commands
The modem responds to the following commands. In section 2.4, Explanation of the AT
commands, from page 10, the AT commands are described with the associated
parameters.

2.4 Explanation of the AT commands
In this section the AT commands are described in alphabetical order. You will find a list of
all the commands in the previous section. For each command the factory default setting is
given. Generally there is no need to change the default setting.
A/ Repeat last command
The modem responds to this command as if the previous command had
been entered again from the terminal. This command must not be
preceded by AT or be followed by <ENTER>.
AT=x Set S register
This command causes the value x to be assigned to the specified S
register. You can also use the command ATS to set the S register. For
more information see ATS.
AT? Read S register
This command displays the setting of the selected S register. You can use
the command AT= to set the S register. For more information see ATS.
ATAAnswers
The command ATA puts the modem on line and activates the answer
mode. If no carrier is detected during the period specified in register S7
(default 60 seconds), the modem is switched off line.
Any character entered while the connection is being established
immediately clears the attempted connection.
AT\A Maximum MNP block size
The MNP error correction mode is activated and the modem operates with
the set maximum block size as shown in the following table.
0- 64 characters
1- 128 characters (default)
2- 192 characters
3- 256 characters

TORNADO SFM 56.0

ATB CCITT/ RING modulation
With this command, the modem uses CCITT- or RING modulation for
connections with a speed of 300 or 1200 bps, depending on the
parameter entered. The default setting CCITT is used for all other speeds.
0- CCITT modulation (default
1- RING modulation
AT\B Break signal to other modem
With this command, during a connection without error correction the
modem sends a break signal to the other modem, the length of which
depends on the specified parameters. During a connection with error
correction, the break signal is sent by the active error correction protocol,
but without an indication of the length. If there is no connection or FAX
mode is active, the ERROR message is issued.
1 - 9 Length of the break signal in units of 100 ms (default = 3).
(This only applies to connections without error correction.)
AT%C Data compression mode
This command selects the MNP5 and/or V42bis mode for data
compression. This mode can only be used with a connection with error
correction.
0- data compression off
1- MNP5 data compression on
2- V42bis data compression on
3- V42bis and MNP5 on, automatic selection (default)
AT&C DCD status (carrier detect)
This command is used to set the operation of DCD.
0- DCD is always on (not visible on LED indicator)
1- DCD monitors the carrier status on the line (default)
AT#CID Dutch Calling Line Identification

TORNADO SFM 56.0
12 Allied Data Technologies
This option indicates who is calling before answering.An extra
subscription will have to be paid for this option to the relevant telephone
company. The number is displayed between the first and second 'RING'
(see example). The command is as follows:
AT#CID=n
0 - Switch Caller Line Identification off. (default)
1 - Switch Caller Line Identification on with standard format.
2 - Switch Caller Line Identification on without standard format.
Example 1:
AT#CID=1 ; select with standard format
OK
RING
NMBR = 0724749361 ; incoming call
RING ; number calling is 072-4749361
Example 2:
This example shows the non-standard format of CLI. The string between
the first and second RING is displayed in ASCII hexadecimal code.
Opening and closing characters are added. The opening character is a 'D'
(hex 44), the closing character is a 'C' (hex 43).
AT#CID=2 ; select non-standard format
OK
RING
443035333934363238303743 ; incoming call
; number calling is 053-9462807
ATD Dialling
This puts the modem on line and dials the number following the ATD
command.
If you do not specify a telephone number, the modem will be put on line
and will try to establish a connection in originate mode.
The modem waits for the time specified in register S7 (default 60
seconds) for a carrier to establish the connection. If the connection has
not been fully established within that time, the modem goes off line (hangs
up) and you will see the error message "NO CARRIER".

TORNADO SFM 56.0
Allied Data Technologies 13
The following parameters are permitted for telephone numbers. You can
use full stops for legibility. Brackets, hyphens and spaces are ignored.
0-9 Numbers 0 to 9
*The asterisk symbol (only with tone dialling)
#The hash symbol (only with tone dialling)
A-D The DTMF letters A to D
PSelect pulse dialling
T
Select tone dialling
S=n Dial a number from the telephone list (see AT&Z)
!Flash. The modem is switched off line during the time set in
register S29.
WWait for a dialling tone. The modem waits for a dialling tone
before the requested number is dialled. If no dialling tone is
detected within thetime specified in registerS6, the modem is
switched off line and you will see the error message "NO
DIALTONE".
@Wait for silence: The modem waits for silence on the line for at
least 5 seconds before the next dial command is carried out. If
the modem does not detect that 5-second silence during the
time specified in register S7, dialling is interrupted and you will
see the error message "NO ANSWER". If detection of the
engaged tone is switched on, you will get the message
"BUSY". If the modem detects an answer tone before the
waiting time has expired, the connection will be established.
,Dial pause: the modem pauses during the time set in register
S8 before the next number is dialled.
LRepeat last number: the modem repeats the last number
dialled.
;Return to command mode: this command after entry of the
telephone number will return the To r n ad o to command mode
after the commands before the character ';' have been
processed. You can then enter extra AT commands while the
modem is on line. The extra AT commands may also be
entered on the original command line after the character ';'.
The To r n ad o only continues dialling if an extra command
without the character ';' is entered. You can then interrupt the
dialling with the ATH command.

( ), -,
<space>You can use these characters for clarity; they are ignored by
the modem.
AT&D DTR status (Data Terminal Ready)
Determines the response of the modem if DTR is disabled.
0 - If the DTR signal is disabled, the default settings of &Q are affected
as follows:
&Q0,&Q5,&Q6: The DTR signal is ignored and the modem works
as if the signal were enabled. This makes it
possible to work with terminals with no DTR
signal.
&Q1,&Q4: When the DTR signal is disabled, the modem is
switched off line. This will not affect auto-answer.
&Q2,&Q3: When the DTR signal is disabled, the modem is
switched off line. Auto-answer is not possible.
1 - If the DTR signal is disabled, the default settings of &Q are affected
as follows:
&Q0.&Q1,&Q4,
&Q5,&Q6. When the DTR signal is disabled, the modem
responds as if an asychnonous escape code has
been received. The modem returns to the
asynchronous command mode without
disconnecting.
&Q2,A&3. When the DTR signal is disabled, the modem is
switched off line. Auto-answer is not possible.
2 - When the DTR signal is disabled the modem is switched off line and
auto-answer is not possible. This is independent of the &Q setting
(default).
3 - If the DTR signal is disabled, the default settings of &Q are affected
as follows:
&Q0,&Q1,&Q4,
&Q5,&Q6. When the DTR signal is disabled, a soft reset of
the modem is performed as would be done with
the ATZ command. The AT&Y setting determines
which profile is loaded.
