Before You Begin your Installation
The product you have purchased is designed to be
easily installed into most IBM PC or compatible
systems. Many products have large, easy-to-read
legends to allow for the easy configuring of the
product. This installation manual contains detailed
instructions. Most included software has automatic
installation programs to place the software correctly onto your computer.
However, as all computers are configured differently, you may be
required to perform some basic MS-DOS or Windows tasks. If you are
not familiar with basic MS-DOS commands such as DIR, CD, or EDIT,
you should check your MS-DOS manual, or seek assistance from you
local computer dealer to install the product.
How to get Technical Assistance
The dealer that you purchased this product or your computer from is the
first place you should go for technical assistance. The dealer is usually
the most qualified source of help, and is most
familiar with your system and how this product
should be installed. Many dealers have
customer service and technical support
programs, with varying levels of support
offered, depending on your needs and computer knowledge. Please
contact the dealer first whenever a problem occurs. International
customers will find that contacting the place of purchase for assistance
will be much more efficient than contacting Boca Research directly.
If your Dealer Can’t Assist you
If you can’t get assistance from your dealer, the manufacturer provides
varying levels of technical assistance as summarized on the following
page. All phone numbers are based in the United States.

A Word about Simultaneous Voice and Data (SVD)
Your modem may support SVD. Simultaneous Voice and Data
(SVD) is a standard allowing the simultaneous transmission of
voice and data over a single telephone line. The model supporting
this standard will allow you to share modem applications and talk
on the phone with a single standard telephone line. When a phone
call is in SVD mode, any data (e.g., images, 3D-graphics, shared
applications, interactive games) can be shared with a normal
phone conversation over the same analog line.

Optional Accessories (speakerphone models with
microphone and speaker jacks)
The speakerphone version of the modem is equipped with
microphone and speaker jacks for use with headset, speakers and
microphone. (See installation instructions: p.16-17.) The handset
can be used to record outbound messages. However, a
microphone is recommended for better quality recordings. You
may use a combination headphone and microphone or a separate
microphone and speaker(s).
Microphone Requirements:
The microphone element must be of the electret type also known
(incorrectly) as a condenser type. The microphone in most telephone
handsets is of this type. This modem was designed for a microphone
sensitivity of -64 dBspl. Other microphone sensitivities work equally
well, with only a subjective difference in loudness. Carbon
microphone elements will also work, but don’t offer the quality of the
electret. Another common microphone element is the dynamic type
which will NOT work with this modem.
Speaker Requirements:
You can attach the modem to a high-quality amplified external
speaker or the earpiece of a handset. The external speaker must have
an impedance rating of 8 ohms or more.

the modem, the user shall discontinue use until it is repaired. In the event
service is needed the user should contact the vendor from whom you
purchased the modem.
Telephone Connection Requirements
Except for telephone company-provided ringers, all connections to the
telephone network shall be made through standard plugs and standard
telephone company-provided jacks, or equivalent, in such a manner as to
allow for easy and immediate disconnection of the terminal equipment.
Standard jacks shall also be arranged that, if the plug connected thereto is
withdrawn, no interference to the operation of the equipment at the
customer’s premises which remains connected to the telephone network, shall
occur by reason of such withdrawal.
Incidence of Harm
Should terminal equipment or protective circuitry cause harm to the telephone
network, the telephone company shall, where practical, notify the customer
that temporary discontinuance of service may be required; however, where
prior notices are not practical, the telephone company may temporarily
discontinue service if such action is deemed reasonable in the circumstances.
In the case of such temporary discontinuance, the telephone company shall
promptly notify customers and will be given the right to bring a complaint to
the FCC if they feel the disconnection is not warranted.

Changes in Telephone Company Equipment or Facilities
The telephone company may make changes in its communications
facilities, equipment, operations, or procedures, where such action is
reasonably required and proper in its business. Should any such changes
render the customer’s terminal equipment incompatible with the
telephone company facilities, the customer shall be given adequate
notice to make modifications to maintain uninterrupted service.
General
The FCC prohibits customer-provided terminal equipment be connected
to party lines or to be used in conjunction with coin telephone service.

code is transmitted after any modulation, error control or data
compression reports are transmitted, and before any final result
code (e.g., CONNECT) is transmitted. The <rate> is applied after
the final result code is transmitted.
The DTE-modem port rate will change only if neither buffered mode
nor error controlled means are enabled (+ES=x,0) and if the
negotiated carrier rate (+MRR) does not match the current DTEmodem port rate (autodetected from the previous command line).

Call Control
D - Dial
This command directs the modem to go on-line, dial according to
the entered string and attempt to establish a connection. If no dial
string is supplied, the modem will go on-line and attempt the
handshake in originate mode. In W-class models, the action of
going off-hook is affected by the status of the Line Current Sense
input, if line current sensing is enabled, and by the blacklist and
delayed list.
NOTE: If the ATD command is issued before the S1 register has
cleared, the modem will respond with the NO CARRIER result
code.
If +FCLASS=0 is selected, the modem will behave as a data
modem and will attempt to connect to another data modem. The
modem will have up to the period of time specified by register S6 or
S7 to wait for carrier and complete the handshake. If this time

expires before the modem can complete the handshake, the
modem will go on-hook with the NO CARRIER response. This
command will be aborted upon receipt of any DTE character before
completion of the handshake.
If +FCLASS=1 or 1.0 is selected, the modem will behave as a
facsimile modem and attempt to connect to a facsimile machine (or
modem) by entering the HDLC V.21 channel 2 receive state (as if
+FRH=3 had been issued). This command will be aborted upon
receipt of any DTE character if the modem has not finished dialing.
In this case, the modem will go on-hook and return to command
mode after displaying the NO CARRIER message. If the modem
finishes dialing, it will proceed as if the +FRH=3 command is
issued. (Refer to the +FRH command to determine how the modem
behaves following this stage.)

enabled. (Most countries do not require Line Current Sense.)
Operation is also dependent upon +FCLASS command and
country-specific requirements.
If +FCLASS=0 is selected, the modem will enter the connect state
after exchanging carrier with the remote modem. If no carrier is
detected within a period specified in register S7, the modem will
hang up. Any character entered during the connect sequence will
abort the connection attempt.
If +FCLASS=1.0 is selected, the modem will go off-hook in V.21

Defined Values
<carrier>
A string which specifies the preferred modem
carrier to use in originating or answering a
connection. <carrier> values are strings of up
to eight characters, consisting only of numeric
digits and upper case letters. <carrier> values
for ITU standard modulations take the form:
<letter><1-4 digits><other letters as needed>.

The modem may also automatically switch to another modulation
(automode), subject to several constraints:
1. The modem may not support some
other modulations, regardless of the
automode mechanism supported.
AT Command Reference
manual2.p65
59
5/4/98, 12:38 PM
60
2.
The modem may not be able to
automatically switch from the current
modulation <carrier> to some other
modulations, restricted by the
selected modulation standard and
by the modem manufacturer’s
technology. For example, there is no
standard way to automode from
V.32bis to V.27ter.
3. The DTE may disable automode
operation, see <automode> below.
4. The DTE may constrain the range of
modulations available, see
<min_rate> and <max_rate> below.
5. The DTE may selectively disable
some modulations by reading,
editing and writing the +MA
parameter.
If the DTE issues a +MS=<carrier> command
to the modem, and if the modem supports
the +MA parameter, the modem will
reinitialize the +MA parameter.
<automode>
An optional numeric value which enables or
disables automatic modulation negotiation
(e.g., ITU-T V.32bis Annex A or V.8). The
default value is enabled if it is defined for the
associated modulation (e.g., ITU-T V.32bis,
V.8 for V.34); however, there are modulations
for which there is no automatic negotiation
defined (e.g., V.26bis).
0=
Automode disabled.
1=
Automode enabled, with V.8
or V.32bis Annex where
applicable. (Default.)
For <automode> = 0 (automode disabled, i.e.,
fixed modulation):
1. If <max_rate> is within the rates
supported by the selected
modulation, the selected rate is that
specified by <max_rate>. For
example:

61
2.
+MS=V32B,0,1200,4800
selects V.32 bis 4800 bps
fixed rate.
If <max_rate> is greater than the
highest speed supported by the
modulation specified by <mod>, the
starting rate is the highest rate
supported by the selected
modulation. For example:
+MS=10,0,2400,14400
selects V.32 bis 14400,
12000, 9600, 7200, or 4800
bps.
For <automode> = 1 (automode enabled, i.e.,
automatically selected speed and
modulation):
1. The modem connects at the highest
possible rate in accordance with V.8
bis/V.8, or V.32 bis Annex A if V.8
bis/V.8 is not supported by the
remote modem.
2. If <max_rate> is greater than the
highest rate supported by the
modulation specified by <mod>, the
modem automodes down from the
highest rate of the selected
modulation. For example:
+MS=V32B,1,1200,14400
selects automoding down
from V.32 bis 14400 bps.
<min_rate> and
<min_rx_rate>
Optional numeric values which specify the
lowest value at which the modem may
establish a connection. If unspecified (set to
0), they are determined by the modulation
means selected in the <carrier> and
<automode> settings. Values for this
subparameter are decimal encoded, in units
of bit/s. The value range is 75-56000 in the
following increments: 75, 300, 600, 1200,

means selected in the <carrier> and
<automode> settings and by the current DTEmodem rate. Non-zero values for this

associated carrier. (Default = Highest rate
supported by the selected carrier.)
<min_rx_rate> and
<max_rx_rate>
May be used to condition distinct limits for the
receive direction as distinct from the transmit
direction. For example, these can be used to
select either direction for asymmetric
modulations like V.23 with constant carrier.
The value range is 75-56000 in the following
increments: 75, 300, 600, 1200, 2400, 4800,

Data Compression Commands
This section contains parameters to condition modem use of
standard ITU-T V.42bis Data Compression Procedures.
+DS - Data Compression
This extended-format compound parameter controls the V.42bis
data compression function if provided in the modem. It accepts four
numeric subparameters:
Syntax
+DS=[<direction>[,<compr_neg>[,<max_dict>[,<max_string>]]]]
Defined Values
<direction>
Specifies the desired direction(s) of operation
of the data compression function; from the
DTE point of view.
<compr_neg>
0=
Negotiated; no compression
(V.42bis P0=0).
3=
both directions, accept any
direction (V.42bis P0=11).
(Default.)
Specifies whether or not the modem should
continue to operate if the desired result is not
obtained.
0=
Do not disconnect if V.42bis is
not negotiated by the remote
modem as specified in
<direction>.
<max_dict>
Specifies the maximum number of dictionary
entries (2048 entries) which should be
negotiated (may be used by the DTE to limit
the codeword size transmitted, based on its
knowledge of the nature of the data to be
transmitted).
<max_string>
Specifies the maximum string length (32
bytes) to be negotiated (V.42bis P2).

The +DR: <type> reported represents the current (negotiated or
renegotiated) modem-modem data compression type. If enabled,
the intermediate result code is transmitted at the point after error
control negotiation (handshaking) at which the modem has
determined which data compression technique will be used (if any)
and the direction of operation. The +DR intermediate result code, if
enabled, is issued after the Error Control Report (+ER) and before
the final result code (e.g., CONNECT).The format of this result
code is:

AT=x - Write to Selected S-Parameter
This command writes the value x to the currently selected SParameter. An S-Parameter can be selected by using the ATSn
command. All of the S-Parameters will return the OK response if x
is a number. Some registers may not be written due to country
specific PTT limitations.
Syntax

AT? - Read Selected S-Parameter
This command reads and displays the selected S-Parameter. An SParameter can be selected by using the ATSn command.
Syntax
S=?
Result Codes
OK
For all arguments.
Sn - Read/Write S-Parameter
The modem selects an S-Parameter, performs an S-Parameter
read or write function, or reports the value of an S-Parameter.
n
Establishes S-Parameter n as the last register
accessed.
n=v
Sets S-Parameter n to the value v.
n?
Reports the value of S-Parameter n.
The parameter n can be omitted, in which case the last SParameter accessed will be assumed. The S can be omitted for AT=
and AT?, in which case the last S-Parameter accessed will be
assumed.
For example:
ATS7 establishes S7 as the last accessed
register.
AT=40 sets the contents of the last register
accessed to 40.
ATS=20 sets the contents of the last register
accessed to 20.
If the number “n” is beyond the range of the S-Parameters
available, the modem will return the ERROR message. The value
“v” is “MOD”ed with 256. If the result is outside the range permitted
for a given S-Parameter the values will still be stored, but
functionally the lower and higher limits will be observed. Input and
output are always in decimal format. Note that some S-Parameters
are read-only.

In some cases, writing to the S-Parameter will appear to be
accepted but the value will not actually be written.
Factory Defaults
The factory default values are stored in Product Configuration File
and are loaded into the active configuration at power up or by the Z
command. In addition, the default profile is subsequently loaded,
and may change some of the factory default values.
The default values in Product Configuration File may be loaded at
any time by entering the &F command.
S-Parameter Definitions
S0 - Number of Rings to Automatic Answer
S0 sets the number of the rings required before the modem
automatically answers a call. Setting this register to zero disables
auto-answer mode.
Range: 0-255 rings
Default:
0
S1 - Ring Counter
S1 is incremented each time the modem detects a ring signal on
the telephone line. S1 is cleared if no rings occur over an eight
second interval.
Range: 0-255 rings
Default:
0
S2 - Escape Character
S2 holds the decimal value of the ASCII character used as the
escape character. The default value corresponds to an ASCII ‘+’. A
value over 127 disables the escape process, i.e., no escape
character will be recognized.
Range: 0-255, ASCII decimal
Default:
43 (+)

S3 - Line Termination Character
S3 sets the decimal value of the command line and result code
terminator character. Pertains to asynchronous operation only.
Range: 0-127, ASCII decimal
Default:
13 (Carriage Return)
S4 - Response Formatting Character
S4sets the decimal value of the character generated by the modem
as part of the header, trailer, and terminator for result codes and
information text, along with the S3 parameter (see the description
of the V parameter for usage). If the value of S4 is changed in a
command line, the result code issued in response to that command
line will use the new value of S4.
The Response Formatting character is output after the Line
Termination character if verbose result codes are used.
Range: 0-127, ASCII decimal
Default:
10 (Line Feed)
S5 - Command Line Editing Character
S5s sets the decimal value of the character recognized by the
modem as a request to delete from the command line the
immediately preceding character. The modem will not recognize the
Command Line Editing character if it is set to a value that is greater
than 32 ASCII. This character can be used to edit a command line.
When the echo command is enabled, the modem echoes back to
the local DTE the Command Line Editing character, an ASCII space
character and a second Command Line Editing character; this
means a total of three characters are transmitted each time the
modem processes the Command Line Editing character.
Range: 0-32, ASCII decimal
Default:
8 (Backspace)

S6 - Wait Time for Dial Tone Before Blind Dialing, or After “W” Dial
Modifier (W-Class Models)
S6 sets one of two possible parameters:
1.
Sets the length of time, in seconds, that the modem will wait before
starting to dial after going off-hook when blind dialing. This
operation, however, may be affected by some ATX options
according to country restrictions. The “Wait for Dial Tone” call
progress feature (W dial modifier in the dial string) will override the
value in register S6.
2.
For W-class models, S6 sets the length of time, in seconds, that the
modem will wait for dial tone when encountering a “W” dial modifier
before returning NO DIAL TONE result code.
The modem always pauses for a minimum of 2 seconds, even if the
value of S6 is less than 2 seconds.
Range: 2-255 seconds
Default:
2
S7 - Wait Time For Carrier After Dial, For Silence, or For Dial Tone
After “W” Dial Modifier (US Models)
S7 sets one of three possible parameters:
1.
Sets the length of time, in seconds, that the modem will wait for
carrier before hanging up. The timer is started when the modem
finishes dialing (originate), or 2 seconds after going off-hook
(answer). In originate mode, the timer is reset upon detection of
answer tone if allowed by country restrictions.
2.
Sets the length of time, in seconds, that modem will wait for silence
when encountering the @ dial modifier before continuing with the
next dial string parameter.
3.
For US models, S7 sets the length of time, in seconds, that the
modem will wait for dial tone when encountering a “W” dial modifier
before continuing with the next dial string parameter.
Range:
1-255 seconds
Default: 50
S8 - Pause Time For Dial Delay
S8 sets the time, in seconds, that the modem must pause when the
“,” dial modifier is encountered in the dial string.
Range: 0-255 seconds
Default:
2

S10 - Lost Carrier To Hang Up Delay
S10 sets the length of time, in tenths of a second, that the modem
waits before hanging up after a loss of carrier. This allows for a
temporary carrier loss without causing the local modem to
disconnect. When register S10 is set to 255, the modem functions
as if a carrier is always present.
The actual interval the modem waits before disconnecting is the
value in register S10 minus the value in register S9. Therefore, the
S10 value must be greater than the S9 value or else the modem
disconnects before it recognizes the carrier.
Range: 1-255 tenths of a second
Default:
14 (1.4 seconds)
S11 - DTMF Tone Duration
S11 sets the duration of tones in DTMF dialing (US models only).
This value has no effect on pulse dialing.
For W-class models, this parameter is a country parameter loaded
by the Product Configuration File.
Range: 50-255 milliseconds
Default:
95 (95 milliseconds)
S12 - Escape Prompt Delay (EPD)
S12 defines the maximum period, in fiftieths of a second, allowed
between receipt of the last character of the three escape character
sequence from the DTE and sending of the OK result code to the
DTE. If any characters are detected during this time, the OK will not
be sent. Note that sending of the OK result code does not affect
entry into command mode. (See 3.1.3.)
Range: 0-255 1/50 of a second
Default:
50 (1 second)

S29 sets the length of time, in units of 10 ms, that the modem will
go on-hook when it encounters the flash (!) dial modifier in the dial
string. The time can be limited as it is a country dependent
parameter.
Range: 0-255 10 ms intervals

RESULT CODES
General
The modem responds to commands from the DTE and to activity
on the line by signaling to the DTE in the form of result codes. The
result codes that the modem can send are described below.
Two forms of each result code are available: long-form, an Englishlike “verbose” response, and short-form, a data-like numeric
response (included in parentheses following the long-form). The
long-form code is preceded and terminated by the sequence < CR>
< LF>. The short-form is terminated by < CR>, only with no
preceding sequence.
If result messages are suppressed, nothing is returned to the DTE.
The long-form results codes can be modified by the OEM through
the Product Configuration File.
The table which follows on the next page lists each result code
short form (ATV0), result code long form (ATV1), and the
corresponding n value in the ATVx command.

Description of Result Codes
OK (0)
The OK code is returned by the modem to acknowledge execution
of a command line.
CONNECT (1)
The modem will send this result code when a connection has been
established and the modem is switching from command state to
online data state:
CONNECT XXXX (1)
For X1, X2, X3, and X4, the modem sends this result code when
the DTE speed is XXXX bps and the modem has been instructed to
report the DTE speed to the DTE upon connecting. (Also, see the
W command.)
RING (2)
The modem sends this result code when incoming ringing is
detected on the line. What qualifies as a ring signal is determined
by country-dependent parameters, modifiable through the Product
Configuration File. When cellular interface is selected, RING
indicates that the cellular phone is receiving an incoming call.
NO CARRIER (3)
The modem sends this result code when an attempt o establish a
connection fails or an established connection has been terminated
Under X0, if busy tone detection is enforced, this result code is
used as a response to the detection of busy or circuit busy. Under
X0, if dial tone detection is enforced or selected, this result code
indicates that dial tone has not been detected.
ERROR (4)
The modem returns this result code if the command is not
recognized (e.g., the command line has a syntax error or the
command is not supported), the command line maximum length is
exceeded, a parameter value is invalid, or other problem with
processing the command line is detected. Under X0, X1, X2, and
X3, this result is used instead of DELAYED and BLACKLISTED.

5/4/98, 12:38 PM
83
NO DIALTONE (6)
For X2 and X4, the modem sends this result code if it has been
instructed to wait for dial tone during dialing but none is received.
When cellular phone interface is selected, NO DIALTONE indicates
that cellular service is not currently available.
BUSY (7)
For X3 and X4, if busy tone detection is enforced, the modem
sends this result code when attempting to originate a call if the
busy (engaged) signal is detected on the line.
NO ANSWER (8)
The modem sends this result code when:
1. Attempting to originate a call if a continuous ringback signal is
detected on the line until the expiration of the timer S7.
2. “@” (Wait for Quiet Answer) dial modifier was used, but remote
ringing followed by five seconds of silence was not detected before
expiration of the connection timer (S7)
DELAYED (24)
For X4, the modem returns this result code when a call fails to
connect and the number dialed is considered ‘delayed’ due to
country blacklisting requirements.
BLACKLISTED (32)
For X4, the modem returns this result code when a call fails to
connect and the number dialed is considered ‘blacklisted’.
FAX (33)
The modem returns this result code when a fax modem connection
is established in a facsimile mode.
DATA (35)
The modem returns this result code when a data modem
connection is established in a facsimile mode.
+FCERROR (+F4)
This message is sent to the DTE when high speed fax data (V.27,
V.29, V.33, or V.17) is expected and a V.21 signal is received.

AUDIOSPAN* AND DSVD Commands
*future implementation
AudioSpan and DSVD are two technologies that allow simultaneous
voice and data operation. AudioSpan and DSVD implementations
differ in the manner that voice and modem data are combined.
Voice and data channels are combined in the analog domain for
AudioSpan and in the digital domain for DSVD.
Establishing a AudioSpan or DSVD connection is analogous to
establishing a regular data modem connection. Initiate the call
using normal dialing (ATD) and answering (ATA) procedures. The
modem can switch from a regular phone conversation into
AudioSpan or DSVD mode and back to phone conversation. A
handset, headset, or microphone/speaker can be used for voice
communication during AudioSpan or DSVD mode.
AudioSpan operates in normal (non-error corrected) or errorcorrected/compression mode (MNP 5 or V.42 bis depending on the
error correction settings of the modems). The DTE rate must be
equal to or greater than the anticipated modem connection speed.
In general, DTE speed of 38400 bps or higher should be used.
-SSE - Enable/Disable DSVD
This command enables/disables DSVD according to the supplied
parameter.
Syntax
-SSE=[<value>]
Defined Values
<value>
Decimal number corresponding to the selected option.
0=
Disable DSVD. (Default.)
1 =
Enable DSVD. A modem not supporting DSVD
will respond with ERROR.
