7 Function Overview
The INSYS Modem 56k AC/DC 4.2 provides the following functions:
230V (AC) power supply
The INSYS Modem 56k AC/DC 4.2 has an integrated power supply.
As an alternative, the INSYS Modem 56k AC/DC 4.2 can be supplied
with 230V AC instead of using a DC power supply. In this case, no external power supply will be required. For redundancy purposes, the
INSYS Modem 56k AC/DC 4.2 can additionally be operated with both
power sources
Automatic Baud Rate Detection
The INSYS Modem 56k AC/DC 4.2 will automatically adjust the data
transmission rate, if a connection is made via its serial interface. The
serial transmission rate can be preset for applications for the serial
communication to be able to initialize with a defined baud rate.
Data buffer for serial data transmission
The INSYS Modem 56k AC/DC 4.2 has a fast send and receive buffer
(cache) to adjust the modem to the operating speed of the application.
Bit Direct Mode
The INSYS Modem 56k AC/DC 4.2 can forward incoming data with-
out having any influence on their transmission format.
Hardware and software data flow control
The INSYS Modem 56k AC/DC 4.2 can transmit to the application via
the control lines of the serial interface to interrupt the dataflow, if the
buffers of the INSYS Modem 56k AC/DC 4.2 exceed a certain level.
An application can also prompt the INSYS Modem 56k AC/DC 4.2 via
a control line to interrupt the data flow. As an alternative, the INSYS
Modem 56k AC/DC 4.2 can control the data flow via XOFF/XON characters in the data stream.
Error correction
The INSYS Modem 56k AC/DC 4.2 has the following error correction
protocols: V.42, V.42bis, V.44, MNP2, MNP3, MNP4, and MNP10

from phone numbers that were previously stored.
Function Overview
INSYS Modem 56k AC/DC 4.2
26
Switch inputs and alarm outputs for SMS dispatch and to establish an
alarm data connection
The INSYS Modem 56k AC/DC 4.2 has two potential-free switch out-
puts, which can be used to switch other functions in an application.
The INSYS Modem 56k AC/DC 4.2 also has digital switch inputs,
which are used to establish connections or to send messages via
SMS and fax.
Sending messages via data connection, SMS or Fax
The INSYS Modem 56k AC/DC 4.2 can send up to 10 previously en-
tered messages to any defined recipient via an AT command. The
dispatch can also be triggered by switching the alarm inputs. Several
transmission paths are possible, such as Fax and SMS.
Pulse input to send up to 10 SMS messages
The SMS to a previously defined recipient can be triggered via the
number of pulses at an alarm input.
Remote configuration
The INSYS Modem 56k AC/DC 4.2 can be configured remotely with
the help of a common modem and a terminal program.
Remote switching of the outputs and queries of the inputs via DTMF
The switching outputs at the INSYS Modem 56k AC/DC 4.2 can be
set remotely with the help of DTMF digits sent from a common
phone. The alarm inputs can be selected via a DTMF phone and queried acoustically.
Access control
The INSYS Modem 56k AC/DC 4.2 can be protected from unauthor-
ized access via a phone connection. An incoming connection must
first be enabled with a password. Using security callback, the INSYS
Modem 56k AC/DC 4.2 calls a previously defined phone number back,
when a call comes in.
Idle connection control with Data Transmit Control
Data Transmit Control enables the INSYS Modem 56k AC/DC 4.2 to
terminate the connection, if no data is transmitted during a defined
state. This will prevent unnecessary costs.
Priority circuit for phones connected in series to the INSYS Modem
56k AC/DC 4.2
The priority circuit prevents that a phone which is connected to the
INSYS Modem 56k AC/DC 4.2 in series is affected by the modem operation. The modem keeps the line free for phone operation. The INSYS Modem 56k AC/DC 4.2 recognizes the states of the phone line at
the individually adjustable voltages.

10 Operating Principle
This chapter describes the basis procedures to operate and configure a INSYS
Modem 56k AC/DC 4.2. It will also give you an overview of the control elements of
the software HSComm.
You have two possibilities to operate and configure the INSYS Modem 56k AC/DC
4.2. In general, the INSYS Modem 56k AC/DC 4.2 is configured and operated via
AT commands. You can enter these commands yourself with the help of a terminal
program and the AT command reference. As an alternative, you can enter the most
important functions easily with the help of the configuration software HSComm.
10.1 Operation with the Terminal Program
In general, any terminal program may be used. We recommend the program
TeraTerm by T. Teranishi. It is available free of cost on the Internet at
http://hp.vector.co.jp/authors/VA002416/teraterm.html.

11 Functions
11.1 Establishing or Accepting a Data Connection
The INSYS Modem 56k AC/DC 4.2 can call another modem via the phone line and
establish a data connection. After dialling a phone number, the INSYS Modem 56k
AC/DC 4.2 synchronises with the called modem and opens a data connection with
the transmission speed, which is currently set at the serial interface. All incoming
characters are transmitted to the other (called) modem during the active data
connection. Therefore, AT commands are not processed during a connection. The
INSYS Modem 56k AC/DC 4.2 must be changed to command mode again using an
"Escape sequence" that it processes AT commands again during an active
connection. Then, the local INSYS Modem 56k AC/DC 4.2 processes the entered
characters as AT commands and does not transmit them to the remote terminal. A
remote INSYS Modem 56k AC/DC 4.2 can be changed to command mode during
an active data connection using the function "Remote configuration".
The INSYS Modem 56k AC/DC 4.2 can accept an incoming connection in the same
way. For this, the "application" or the PC with the terminal program at the serial
interface must have DTR signalling enabled, otherwise, the INSYS Modem 56k
AC/DC 4.2 does not accept the incoming connection. In this case, DTR signalling
must be disabled in the INSYS Modem 56k AC/DC 4.2 that a connection is
accepted regardless of the status of the application. The status of the hardware
data flow control (enabled by default) must also be considered. It answers after the
configured number of ring tones and opens a connection.

11.3 Automatic Baud Rate Detection
11.3.1 Serial Connection
The automatic baud rate detection enables a continuous automatic adjustment of
all parameters (baud rate, data format) of the serial interface at the INSYS Modem
56k AC/DC 4.2. The device will detect during the operation, which baud rate and
which data format is applied to the serial interface. After a restart, the INSYS
Modem 56k AC/DC 4.2 will restore the last working interface configuration. With
each incoming AT command (according to the character string "AT"), the
parameters for the interface of the INSYS Modem 56k AC/DC 4.2 will be checked
and adjusted, if necessary. This is the reason why the baud rate can not be stored
with the command AT&W, as the INSYS Modem 56k AC/DC 4.2 will immediately
adjust its interface to the current parameters of the currently established serial
connection.
The function is active as default.
Configuration with HSComm
A configuration using HSComm is not possible, because the automatic
baud rate detection will re-adjust the baud rate of the serial interface at
the INSYS Modem 56k AC/DC 4.2 immediately after each further "AT".
As the software sends several commands, entering an AT command to
temporarily change the baud rate in the field "Initialization string" will at
best be ineffective. It can also result in errors during the transmission of
the settings from the software to the INSYS Modem 56k AC/DC 4.2.
Configuration with AT commands
The INSYS Modem 56k AC/DC 4.2 must be configured with the baud
rate, which is used to operate the application at a later time, as the
INSYS Modem 56k AC/DC 4.2 will always use the last known functioning
configuration of its interface.

To display the current settings:

For a list of possible parameter of the
command, enter:
AT+MS=?
11.3.2 Phone Connection
The automatic negotiation of the baud rate and the modulation standard enables
the INSYS Modem 56k AC/DC 4.2 to negotiate the largest possible connection
speed to the remote terminal while the connection is established. The speed
depends on the settings and the abilities of the modem at the remote terminal. Via
the modulation standard, the connection speed can be set through the phone line.
If nothing is defined, the INSYS Modem 56k AC/DC 4.2 will automatically try to
determine the optimum connection parameters.
The function is active as default.
Configuration with HSComm
A direct configuration with the HSComm is not intended. The AT
command to define a fixed baud rate can be sent to the INSYS Modem
56k AC/DC 4.2 via the entry field "Initialization string" (Page 36, Figure 7:
HSComm Modem - Modem, Position 13).
Configuration with AT commands
Please find the possible parameters for this command in the Chapter "AT
Command reference".
11.4 Data Buffer for Serial Data Transmission
The INSYS Modem 56k AC/DC 4.2 provides send and receive buffers. These
buffers prevent the loss of data, in case the application or the remote terminal can
not receive data at this time. The data buffer can be deactivated together with the
error correction (bit direct mode). When the buffer is activated, the data flow
control should be active to avoid a buffer overflow in the INSYS Modem 56k AC/DC
4.2. If the buffer overflows, the data gets lost. Operation without a buffer and error
correction is only useful for special character framings.
The function is active as default.
Configuration with HSComm

For special applications, the buffering of the INSYS Modem 56k AC/DC 4.2 can be
deactivated using the setting "unbuffered, bit direct". All data is forwarded without
buffering and further influence of the INSYS Modem 56k AC/DC 4.2. This applies
especially to the parity and stop bits. The error correction and the data compression
are in this case switched off as well. If the INSYS Modem 56k AC/DC 4.2 is
operated in this mode, not all functions will be available. The remote configuration
and all functions for which a password is required, will no longer be available. This
mode should only be used for special character framings.

11.6 Data Flow Control (Handshake)
The data flow control ensures that the data transfer is interrupted as soon as the
modem buffer exceeds a certain level. Two data flow control options are available:
Via the control lines RTS and CTS, or via the control characters XON/XOFF which
are inserted into the data stream.
11.6.1 Hardware data flow control (RTS/CTS)
The hardware data flow control works in two directions. When the critical buffer
level is exceeded, the modem will set the CTS line to "low" and will thus indicate to
the application to interrupt the dataflow. When the buffer is emptied sufficiently for
the INSYS Modem 56k AC/DC 4.2 to be able to receive data again, the CTS line is
set to "high". Reversely, the application can also indicate to the INSYS Modem 56k
AC/DC 4.2 to interrupt the data flow. This is done via the RTS line. If it is set to
"low", the modem will interrupt the data flow to the application. The application
will set it to "high" to request data from the INSYS Modem 56k AC/DC 4.2.
The data flow control with RTS/CTS behavior is active by default.

11.6.2 Software data flow control (XON/XOFF)
When the input buffer of the modem exceeds a certain fill state, the modem will
insert an XOFF character into the data stream to the application. This character will
cause the application to send no more data. It will depend on the according
application software if the XON/XOFF data flow control is supported.
After the input buffer of the modem is emptied so much that data can be received
again, the modem will send an XON character to the application. This character will
cause the application to send data to the modem again. Analogously, the
application can insert XON/XOFF characters into the data stream to switch the data
flow on and off. The XON/XOFF data flow control is only available when the
transmitted data do not contain the characters XON or XOFF, which usually appear
only in actual ASCII texts (7 bit). When binary data (programs, etc.) are transmitted,
or in the XMODEM transmission protocol, for example, occasionally appearing
XON or XOFF characters would disturb the operation.

The INSYS Modem 56k AC/DC 4.2 masters the V.42 error correction protocol
including the Microcom Networking Protocol Levels 2/3/4 (MNP2, MNP3, MNP4)
and the data throughput optimization MNP10. The V.42 error correction includes
the protocols LAPM (Link Access Procedure for Modem) and MNP4. LAPM is the
preferred error correction. MNP 4 is supported to maintain the compatibility with
other MNP modems. Both methods determine frames to transfer net data and use
CRC (Cyclic Redundancy Check) check sums for error tests. In V.42, there is the
option to have the modem identify if the partner is a V.42 modem, a MNP modem,
or a modem without error correction. The modem can then autonomously adjust to
the partner.
As default, the automatic selection of V.42LAPM or MNP4 or no correction is set.

11.8 Data Compression
The INSYS Modem 56k AC/DC 4.2 supports various data compression types.
During the connection setup, it will automatically detect the type of data
compression used by the remote terminal, or it is set to a certain type of data
compression. Data compression is only available for error corrected connections.
To be able to use data compression, both sides (sender and recipient) must be able
to at least recognize and support the same data compression mode.
The default setting is the automatic selection of MNP 5 and V.42bis and V.44 data
compression (AT%C3).
Configuration with HSComm
Direct configuration with the HSComm is not intended. The AT

11.9 Selective Call Acceptance
The selective call acceptance enables to define, which calls are accepted by the
INSYS Modem 56k AC/DC 4.2. If the selective call acceptance is activated, the
INSYS Modem 56k AC/DC 4.2 will only accept calls from previously defined callers.
The INSYS Modem 56k AC/DC 4.2 will identify the caller via CLIP. This must,
however, be supported by the network provider or the phone system, where the
modem is connected to. The list of phone numbers of the INSYS Modem 56k
AC/DC 4.2 has 8 storage locations altogether (N0 to N7).
The INSYS Modem 56k AC/DC 4.2 checks in the phone number transmitted via
CLIP, whether one of the numbers stored in the list is contained. The check will be
started „from right“, i.e. the end of the phone number transmitted via CLIP. This
enables to recognize a phone number even if „+49“ or „0049“ or a different prefix
has been put in front. Moreover, the number stored for recognition can remain
variable using „wildcards“ at certain positions. The stored phone number must not
contain separators, like hyphens between area code and phone number for
example.

11.11 Alarm Inputs
The INSYS Modem 56k AC/DC 4.2 has two digital inputs, which can trigger the
sending of messages when connected to GND. When an alarm occurs, the INSYS
Modem 56k AC/DC 4.2 can send a message either via a data connection, a fax or
an SMS.
The events at the ports are treated in two different ways. Either "simple pulses" are
processed at input 1 and only one single message is sent to only one recipient
(alarming). As an alternative, the number of pulses from the INSYS Modem 56k
AC/DC 4.2 can be counted to send one of 10 certain messages (pulse input). Each
of the 10 messages can be sent to another phone number. If the pulse count is active, an individual event can also be processed at input 2. Events at the input 2 will
always send the message no. 2 from the list of messages.
The INSYS Modem 56k AC/DC 4.2 will evaluate a connection to the first input to
GND as an impulse. This will only count negative flanks. Two "pulse types" are
available: "Simple pulses" and count pulses. If no positive flanks are counted for at
least 4 seconds, a "simple alarm" is processed and the sending of the group message to the defined recipient is triggered. Count pulses are periodic connections to
GND, which do not last longer than two seconds. The length of a pulse or the
pause respectively can have a duration between 0.3 and 2 seconds (Figure 1: Duration of interpulse periods). Depending on the number of count pulses, the messages 1 to 10 are sent.
Figure 9: Duration of interpulse periods
The sent messages consist of the group message and the according message 1 to
10. It is thus possible to specify the system with the group message and to specify
the reported system part in the pulse message.
For control purposes, simple and pulse alarms may be triggered via AT commands.
The status of the alarm inputs can be queried by AT commands or via DTMF tones
(see Chapter 1.

11.12 Sending messages via Data connection, SMS or Fax
The INSYS Modem 56k AC/DC 4.2 monitors its alarm inputs to send a message in
case of an event. The two types of message dispatch are simple "Alarming" and
the pulse count. For simple alarming, one individual message is sent to an
individual number. For impulse counting, a message is sent to the respective
recipient depending on the number of pulses. This message is composed of a
common collective message and an individual message. As a default, three
attempts are made to send a message.
Configuration with HSComm
In order to select the simple alarming or pulse counting, select on the
alarm functions tab in the "Action at Alarm" field either "Impulse input
active" or "Alarm input active" from the drop-down menu (Page 38,
Figure 8: HSComm Modem - Alarm functions tab (pulse input active was
selected), Position 1).
in order to define the connection type for the message dispatch (mobile
phone, modem, fax), select the respective connection type in the dropdown menu (Page 38, Figure 8: HSComm Modem - Alarm functions tab
(pulse input active was selected), Position 11).
In order to specify the recipient for the message dispatch, enter the
recipient number (mobile phone, modem, fax) into the "Phone number"
field below.
A dialling character (e.g. "0") for outside line access in PABXs can be
entered in the "characters for dial prefix" entry field (Page 38, Figure 8:
HSComm Modem - Alarm functions tab (pulse input active was
selected), Position 2). A dialling pause following the outside line access
code can be achived by inserting a comma.
In order to define the message text for a simple alarming, enter a
message text into the "Alarm text" field.
In order to specify a general text (a "collective message") for active
impulse input, which precedes all impulse messages, enter a message
text into the "Common text" text field (Page 38, Figure 8: HSComm
Modem - Alarm functions tab (pulse input active was selected), Position
6).
In order to specify messages for active impulse input for the respective
number of counting pulses, enter the messages for the counting pulses
into the respective entry fields (Figure 8: HSComm Modem - Alarm
functions tab (pulse input active was selected), Position 6). In addition,
enter the recipient number with area code (or also with country code)
into the "Recipient number" entry field for the respective alarm input (38,

11.20 Priority Circuit for a Phone Connected in Series
The INSYS Modem 56k AC/DC 4.2 may give a phone connected in series priority,
to make sure the modem functions interfere as little as possible with the usage of
the phone connection. TheINSYS Modem 56k AC/DC 4.2 can determine on the
basis of the voltage in the line, if the phone line is used by a phone, if a phone in
series is going off-hook or if the remote terminal of the INSYS Modem 56k AC/DC
4.2 is terminating the connection.
The functions of the priority circuit may be combined or used individually. The
functions can be selected and activated with the AT command AT-STE=<n>.
The following table provides the combination of functions with the according AT-
STE command.
Table 14: Possible combinations of the individual functions of the priority circuit
The modem detects the status of the phone line at the voltage levels in the line.
Optionally, the voltages for the various line states can be set with the command
AT-TTE=U1,U2,U3. The voltages U1, U2 and U3 are by default set to functioning
values and need not be modified. The following illustration shows the voltage curve
for the according line state and the appropriate AT command parameters.

State
Description
1
No connection has been established. The line is free.
2
A connection has been established. The telephone is off-hook and connected
to a remote terminal. The voltage in the line has dropped with the amount of
U1. The INSYS Modem 56k AC/DC 4.2 can thus detect that the line is busy.
3
A connection has been established, but this time the INSYS Modem 56k
AC/DC 4.2 occupies the line and is connected to a remote terminal. If the
telephone connected in series goes off-hook, the voltage will drop with the
amount U2. The INSYS Modem 56k AC/DC 4.2 will detect that the phone has
gone off-hook and will terminate the connection.
4
The line is busy during a modem connection. After the remote terminal hangs
up, the INSYS Modem 56k AC/DC 4.2 will detect through the short power
spike U3 (the crackling noise in the line) that the remote terminal has hung up.
This will set the event code of the S registry 86 to 25 (remote terminal has
hung up). This means that the INSYS Modem 56k AC/DC 4.2 will not keep the
line busy for an unnecessarily long period.
If phone systems are used which dampen the crackling noise or the short
power spike, it may occur that the system will not detect that the remote
terminal has hung up.

To use the desired functions of the priority
circuit, use:
AT-STE=<n>
To set the voltage level for the detection of
the line status, use:
U1 is the voltage difference in the phone
line between hung up state (free line) and
the busy line.
U2 is the voltage difference, which is
generated in the phone line when the
INSYS Modem 56k AC/DC 4.2 has already
gone off-hook and a telephone connected
in series is going off-hook.
U3 is the voltage difference in the phone
line between hung up state (free line) and
the busy line.

functions to the INSYS Modem 56k AC/DC 4.2 or to improve the existing functions.
A firmware update can be performed with the help of a terminal program that
supports ASCII uploads (e.g. TeraTerm).
Firmware update with a terminal program
How to load new firmware to the INSYS Modem 56k AC/DC 4.2.
You will need a terminal program that supports ASCII file transfers, such as
TeraTerm.
You will need the firmware that is suitable for your INSYS Modem 56k
AC/DC 4.2.
The INSYS Modem 56k AC/DC 4.2 is connected to the PC.
1. Start your terminal program.
2. Activate hardware handshake in the terminal program.
3. Open the serial interface, to which the INSYS Modem 56k AC/DC 4.2
is connected.
4. Set the baud rate in the terminal program to 57600 baud.
5. Type in "AT" and confirm with "Enter".
The INSYS Modem 56k AC/DC 4.2 responds with OK:
If the INSYS Modem 56k AC/DC 4.2 does not respond, check the
connection and if the device receives power at all. Continue with step
2.
The firmware upload can not function without the hardware
handshake. The input buffer at the serial interface of the INSYS
Modem 56k AC/DC 4.2 flows over and the INSYS Modem 56k AC/DC

4.2 resets itself. In this case, you will hear the relays click during the
upload. It is possible that an error message is displayed.
Before you start with the upload, ensure that no other programs are
active on your system, which could interrupt the data flow at the serial
interface. Opening a DVD drive, playing music or connecting a USB
device can also disturb or interrupt the data flow. As a result, the
INSYS Modem 56k AC/DC 4.2 may fail to function, and only INSYS
MICROELECTRONICS will be able to restore it.
6. Type AT** to start the firmware upload.
The modem reports "Download initiated...".
7. Use the terminal program to send the file with the firmware loader,
such as "HS_LADER.S37".
If you do not send a firmware file, the INSYS Modem 56k AC/DC 4.2
will terminate the procedure after approx. 60 seconds.
The upload progress is displayed by dots in the terminal window.
The INSYS Modem 56k AC/DC 4.2 reports the successful upload of
the firmware loader, for example with

If you didn't receive the previous message for a successful upload, the
upload has most probably failed. Try to reset the INSYS Modem 56k
AC/DC 4.2 and to repeat the process from step 4. If this fails and the
INSYS Modem 56k AC/DC 4.2 does no longer react to AT commands,
please contact the INSYS MICROELECTRONICS support department.
8. Use the terminal program to send the file with the firmware, such as
"20B7.S37".
The upload progress is again displayed by dots in the terminal
window.
After a successful upload, the INSYS Modem 56k AC/DC 4.2 will
display: Device successfully programmed
The INSYS Modem 56k AC/DC 4.2 will reset itself and is ready for
operation.

ATD<n>
Dialing
The INSYS Modem 56k AC/DC 4.2 goes off-hook and dials according to the dialing string transmitted via the ATD command. After the dialing procedure, the
INSYS Modem 56k AC/DC 4.2 attempts to establish a connection. If the ATD
command was performed without a dialing string, the INSYS Modem 56k AC/DC
4.2 goes off-hook and attempts to connect to the other INSYS Modem 56k AC/DC
4.2 (without dialing). The behavior of the INSYS Modem 56k AC/DC 4.2 depends
on the activation of the line current detection (see ATX command).
The execution of the ATD command also depends on when the last dialing
attempt was performed.
In the mode AT+FCLASS=0, the INSYS Modem 56k AC/DC 4.2 acts like a data
modem. It attempts to connect to another data modem. This attempt is repeated
until the waiting period that was specified in the S7 registry has expired.
If this period is exceeded, the INSYS Modem 56k AC/DC 4.2 hangs up and the
following error message appears: NO CARRIER.
In the mode FCLASS=1 or =2, the INSYS Modem 56k AC/DC 4.2 acts as a fax
modem. It attempts to connect to another fax or fax modem. (The INSYS Modem
56k AC/DC 4.2 goes into receive status HDLC V.21 channel 2, as if the command
AT+FRH had been executed.)
The following characters may be transmitted as parameters (brackets, punctuation marks, spaces and semicolons are ignored):
0 to 9 The digits from 0 to 9
* The asterisk: Only for tone dialing
# The hash: Only for tone dialing
A-D The tone dialing characters A, B, C, D
P Pulse dialing mandatory: Pulse or tone dialing is required according
to the region.
T Tone dialing mandatory: Pulse or tone dialing is required according
to the region.
W Wait for dialing tone: The INSYS Modem 56k AC/DC 4.2 waits for
the dialing tone before it starts to dial. If no dialing tone was detected within the period specified in the S6 registry, the INSYS
Modem 56k AC/DC 4.2 hangs up and an error message is displayed.
@ Waiting for silence: The INSYS Modem 56k AC/DC 4.2 waits at
least five seconds for silence in the line, before it executes the next
character from the parameter string. If this five second silence can
not be detected and the abort period in the S7 registry has not
been exceeded, the INSYS Modem 56k AC/DC 4.2 terminates the
connection displaying the message: NO ANSWER.
If busy signal detection was activated, the INSYS Modem 56k
AC/DC 4.2 terminates the connection displaying the message:
BUSY.
If a response tone from the other INSYS Modem 56k AC/DC 4.2 is
received during the waiting period, a connection is established.

; Return to the input mode after dialing. It is added to the end of the
dialing string and causes the INSYS Modem 56k AC/DC 4.2 to return to the entry mode when it reaches “;” (with: message OK).
This enables the input of AT commands even with a receiver offhook. The additional AT commands can follow in the same input
line after the “;” or they can be transmitted to further input lines.
The ATH command will abort the connection and the receiver is
hung up.
S=n Dialing the n-th number from the number pool, which was set up
with the AT&Z<n> command.
! If the character ”!” is a part of the dialing string, the INSYS Modem
56k AC/DC 4.2 will hang up within the time frame determined in
S29 and then goes off-hook again.
^ Suppresses the sending of a ringing tone.

to be able to dial a leading 0 without hearing a dialing tone. After 0
has been dialed via: D0 dialing tone detection can be switched on
again using the parameter: W. The INSYS Modem 56k AC/DC 4.2
thus waits for the dialing tone and continues with the rest of the
dial-up (via: 12345) only after hearing the dialing tone. Waiting for
the dialing tone may be omitted. In this case, the dialing command
is ATX3D012345.

Break control
The INSYS Modem 56k AC/DC 4.2 reacts to a break (receive path OFF for a certain amount of time), which it receives from another modem or from the PC, or
from the command AT\B according to the parameters.
1. Situation In case of a break from the application during the data connection
to another modem:
AT\K0 INSYS Modem 56k AC/DC 4.2 enters the command mode and
sends no break to the other modem
AT\K1 INSYS Modem 56k AC/DC 4.2 deletes the data buffer and sends a
break to the other modem
AT\K2 See AT\K1
AT\K3 INSYS Modem 56k AC/DC 4.2 immediately sends break to the oth-
er modem; data buffers are not deleted.
AT\K4 See AT\K0
AT\K5 INSYS Modem 56k AC/DC 4.2 inserts break into the data transmit-
ted to the other modem
2. Situation During a data connection, the INSYS Modem 56k AC/DC 4.2 was
set to command mode by an escape sequence +++. In this condition, the command AT\B will send a break to the other modem. In
this situation, the parameter n will cause the following:
AT\K0 INSYS Modem 56k AC/DC 4.2 deletes the data buffer and sends a
break to the other modem
AT\K1 See AT\K0
AT\K2 INSYS Modem 56k AC/DC 4.2 sends a break to the other modem
without delay.
AT\K3 See AT\K2
AT\K4 INSYS Modem 56k AC/DC 4.2 inserts a break into the data trans-
mitted to the other modem
AT\K5 See AT\K4 – Return from the online command mode into the data
mode via the ATO command.
3. Situation In the case a break is received from another modem during a connection that has not been error corrected, the parameters cause
the following:
AT\K0 INSYS Modem 56k AC/DC 4.2 deletes the data buffer and sends a
break to the PC
AT\K1 See AT\K0
AT\K2 INSYS Modem 56k AC/DC 4.2 sends a break to the PC without

Description
ATL<n>
Speaker volume
This command regulates the speaker volume (see command ATM).
ATL1 Speaker volume low (default)
ATL2 Speaker volume medium
ATL3 Speaker volume high
AT%L
Display level of the received signal
The value that is reported from the INSYS Modem 56k AC/DC 4.2 equals the already amplified level within the INSYS Modem 56k AC/DC 4.2, not the phone line
level.
Large AT%L responses imply a low signal level; small values imply a high signal
level
(009 = -9db, 043 = -43db)
AT*L<n>
Determines the automatic speed limitation
The automatic speed limitation is used to automatically achieve the least possible
error rate for connections without error correction.
In the factory settings the speed limitation is always switched on (AT*L0).
If the limitation is switched off (AT*L1), the INSYS Modem 56k AC/DC 4.2 will
always establish the connection on the phone side with the maximum possible
speed (or the speed defined with AT+MS), irrespective of the data rate at the serial
interface. This means that the INSYS Modem 336 will, for example, always attempt to establish a 33600 baud connection, even if the serial interface is only set
to 9600 baud. Without error correction the high speed will obviously lead to higher bit error rates, which is usually disruptive.
The automatic speed limitation (AT*L0) will limit the speed on the phone side to
the speed of the serial interface.
It should only be switched off if very low baud rates are employed or if the speed
of the serial interface is changed during the connection.
ATM<n>
Speaker control
This command regulates when the speaker is active
(see command ATL<n>).

a wrong password was entered, the INSYS Modem 56k AC/DC 4.2 will hang up.
The password is the same as for remote control and is set with AT*C.
ATQ<n>
Quiet control
This command toggles sending messages from the INSYS Modem 56k AC/DC 4.2
to the application ON and OFF.
ATQ0 Send messages to application (default).
ATQ1 Don’t send messages to application.
AT%Q
Display telephone call quality
Displays the quality of the data connection (deviation from the eye diagram). Low
values indicate a good line quality. The line quality value must be evaluated differently
depending on the negotiated data rate.
Connections with more than 9600 baud will reach the value “000” for good lines and
should not have values of more than “010”.
For connections with 33600 baud good lines will have values between 010…030.
Depending on the settings and the modulation type a fall back or retrain is triggered if
the line quality is too bad to enable a new negotiation of the connection (if necessary
with a slower speed).
High values indicate bad quality. These values are constantly updated during a
connection. If the value increases significantly during a connection, the quality
will deteriorate. After a previous AT%E command, an
Autoretrain
is performed.

AT\Q<n>
Quiet Call
Quiet Call will switch of the phone connected in series at the first ring. In connection with the selective call answer (AT&N<n>), calls from a previously defined
phone number can take place without a ring of the phone connected in series. If
the phone number is not detected by the INSYS Modem 56k AC/DC 4.2, the
phone is switched on again after the first ring.
AT\Q0 Switches Quiet Call off (default)
AT\Q1 Activates Quiet Call. The phone connected in series is discon-
nected, as soon as an entire ring signal cycle is detected on the line.
AT\Q2 Activates Quiet Call. The phone connected in series is
disconnected, as soon as a ring signal flank is detected on the line.
The selection between the settings \Q1 or \Q2 depends on the circumstances at
the phone connection. For \Q2 in connection with pulse dialing, phones that are
connected in parallel will sometimes result in an erroneous detection of a ring
signal flank. When using pulse dialing at the phones connected in series, AT\Q1
must be used.
AT&R<n>
RTS/ CTS behavior
This command determines how the INSYS Modem 56k AC/DC 4.2 treats the
RTS/CTS (CT105/CT106) data flow control lines.
(See also command AT&K).
AT&R0 CTS behavior complies with V.25bis. CTS is deactivated during the
connection setup after detection of the response or ringing tones
and will only be activated after the connection is set up. During the
controlled half duplex operation (AT&K8) CTS is active, if the INSYS
Modem 56k AC/DC 4.2 sends data at the serial interface. When data is received at the serial interface, CTS is inactive.
AT&R1 CTS only switches to OFF when this is required by the data flow
control. During the controlled half duplex operation (AT&K8) CTS is
inactive, if the INSYS Modem 56k AC/DC 4.2 sends data at the serial interface. When data is received at the serial interface, CTS is
active. (default)

Description
AT&V<n>
Show the configurations
AT&V0 The active configuration of the modem, the saved user defaults and
the saved phone numbers 0 to 3 (the parameter 0 may be omitted)
are displayed.
AT&V1 Displays the diagnostic data of the last connection (connection
partner, reason for disconnect).
TERMINATION REASON: Reason for disconnect.
E.g.: Connection termination via command (ATH: “LOCAL RE-
QUEST”).
LAST TX rate: Last baud rate at the phone line in send direction,
prior to the termination.
HIGHEST TX rate: Highest baud rate that was achieved at the
phone line in send direction, prior to the termination.
LAST RX rate: Last baud rate at the phone line in receive direction, prior to the termination.
HIGHEST RX rate: Highest baud rate that was achieved at the
phone line in receive direction, prior to the termination.
Note: The data rates may vary if a fall forward, fall back or
retrain occurred during the connection. To impact the negotiated
data rate, use the command AT+MS.
PROTOCOL: Displays the used error correction protocol. “LAPM“
equals a V.42 secured connection. For “NONE”, the connection was
not error corrected (the error corrected can be influenced with the
command AT\N).
COMPRESSION: Displays the used data compression method. The
example shows the used compression method V.42bis (the compression method can be set with the command AT%C).
LINE QUALITY: Displays the quality of the data connection (deviation from the eye diagram). Low values indicate a good line quality.
The line quality value must be evaluated differently depending on
the negotiated data rate.
Connections with more than 9600 baud will reach the value “000”
for good lines and should not have values of more than “010”.
For connections with 33600 baud good lines will have values between 010…030. Depending on the settings and the modulation
type a fall back or retrain is triggered if the line quality is too bad to
enable a new negotiation of the connection (if necessary with a
slower speed).
Rx LEVEL: Displays the receive level (which is internally applied at
the modem chip) in –dBm. High values indicate a low input level;
low values indicate a high input level. The optimum receive levels
range from approx. 012 to 028. To high levels could cause distortions; too low levels will cause the line noise to have a negative
impact on the connection quality.
Local Rtrn Count: Number of retrains (renegotiation of the
connection), triggered by the local modem.
Remote Rtrn Count: Number of retrains (renegotiation of the
connection), triggered by the remote modem.
AT&V3 Display of the currently set baud rate (AT*S<n>) as well as the
currently set data format (AT*U<n>).

The command AT+VRID displays the CLIP of the last caller.
AT+VRID=0 displays the ID preformatted.
AT+VRID=1 displays the ID unformatted.
ATW<n>
Error correction messages
This command determines which data transmission rate information is provided
for a CONNECT message.
ATW0 The INSYS Modem 56k AC/DC 4.2 reports the baud rate between
INSYS Modem 56k AC/DC 4.2 and application. (default)
ATW1 During the connection setup, the INSYS Modem 56k AC/DC 4.2
reports the phone line speed, the error correction protocol and the
application baud rate.
ATW2 The INSYS Modem 56k AC/DC 4.2 reports the phone line speed.
AT&W<n>
Save configuration
The command saves the current modem configuration including the S registry in
one of the two user-defined defaults.

Command
Description
ATX<n>
Extended result messages, dial tone detection
The command determines which group of messages the INSYS Modem 56k
AC/DC 4.2 sends to the PC. This is important for PBXs, as a leading 0 or 9 must
often be dialed before a dialing tone is heard on the line.
Blind dialing
(dialing
without detecting the dialing tone) is activated or deactivated according to the
parameter. The detection of the dialing tone, however, can always be enforced
using the parameter W in the ATD dialing string (see command ATD). In the mode
AT+FCLASS=1,2 the INSYS Modem 56k AC/DC 4.2 always sends the message
CONNECT to the PC without specifying the transmission speed.
ATX0 No detection of the dialing tone, i.e. an unsuccessful dialing at-
tempt leads to the message NO CARRIER.
No detection of the busy signal, i.e. when calling a busy line the
message NO CARRIER is displayed. The message is displayed
without specifying the speed.
ATX1 As ATX0, but the CONNECT message contains the speed specifica-
tion.
ATX2 Dialing tone detection is active, i.e. a dialing attempt without the
presence of a dialing tone leads to the message NO DIALTONE.
No detection of the busy signal, i.e. when calling a busy line the
message NO CARRIER is displayed.
ATX3 No detection of the dialing tone, i.e. an unsuccessful dialing at-
tempt leads to the message NO CARRIER.
Busy signal detection active, i.e. when calling a busy line the mes-
sage BUSY is displayed.
ATX4 Dialing tone detection is active, i.e. a dialing attempt without the
presence of a dialing tone leads to the message NO DIALTONE. (default)
Busy signal detection is active, i.e. when calling a busy line the
message BUSY is displayed.
AT*X
Terminate remote configuration
The command AT*X terminates a remote configuration.
AT&Y<n>
Selection of user configuration for hardware reset
AT&Y0 For a hardware reset following the AT&Y0-command, the user de-
fault 0 (created using the AT&W0 command) is loaded into the current modem configuration.
AT&Y1 For a hardware reset following the AT&Y1-command, the user de-
fault 1 (created using the AT&W1 command) is loaded into the current modem configuration.
