Introduction
Thank you for purchasing the Actiontec PCI Pro 56K internal modem. The PCI Pro
incorporates the latest technology in controller-less V.90 modems for the PCI bus.
This technology improves the performance and capabilities of personal computer
fax/modems. The use of the PCI Bus frees the user from having to use an ISA slot
which is most likely already being used by another peripheral. Almost every PC has
at least one free PCI slot.
Host-based or “Windows” modems utilize your computer’s internal Central Process-
ing Unit, or CPU to perform some of their functions. The modem’s onboard digital
signal processing circuitry handles the most processor-intensive functions such as
V.90 and V.34 modulation, while the CPU handles more routine communications
tasks like data compression. This allows for fewer parts and greater reliability without
taxing the overall system speed. It also allows the modem greater access to memory
and disk storage space. As personal computers advance in speed and capabilities,
controller-less modems can take advantage of these improvements. Simply download
the new driver, follow the installation instructions, and reboot your system. In this
way, the performance of your modem improves as your PC hardware improves.

Do This First
Please read the following tips carefully before attempting to install your new modem.
For Windows 95 and Windows 98 Installations
Be sure to remove all other modem drivers from your operating system. To do this,
right-click My Computer, choose Properties from the menu that appears, then click
on the Device Manager tab. Double-click the Modems icon in the list of devices to
show the modems installed. Click once on the icon next to any modems in this list to
select them. When all of the modems are selected, click Remove.
Turn off the computer and physically remove your old modem from the system. Once
you remove the old modem and its drivers from your system, you will need the old modem
driver diskette if you wish to reinstall it at a later date.
Restart the computer. On the taskbar, click Start. On the Start menu, click Settings,
then click Control Panel. Double-click on the Modems icon. Select any and all listed
modems and click Remove. Shut down (rather than restart) the computer. Wait 5
seconds before turning it back on.

If you are going to use the Telephone Answering Machine (TAM) functions of the
modem and you are running Windows 95, you need to install a software component
called Unimodem V. If you have Windows 95 OEM Service Release 2 (Version
4.00.950 B, hereafter referred to in this manual as Windows 95B) or a later version
of Windows, this component comes standard as part of the operating system.
To find out which version of Windows 95 you are using, right-click the My Com-
puter icon on the desktop, and choose Properties from the menu that appears. If the
version of Windows 95 is 4.00.950 or 4.00.950A, go to the UNIMODEM directory
of the CD-ROM that came with your modem and right-click on the UNIMODV.INF
icon, (this may be named UNIMODV) then click on Install.. Restart your computer
to enable the drivers.
In order to support older software, the modem will always be assigned to COM 4.
This port assignment is made by Windows based on instructions contained in the
.INF file supplied with the modem. Check Device Manager and verify that COM 4
is not listed.
Right-click on the My Computer icon, choose Properties, and select the Device
Manager tab. From the device tree, double-click the Ports [COM & LPT] icon to
expand the list of ports. COM 1 and COM 2 should be listed. If COM 4 is listed, it
is in use, it must be made available as the modem will be automatically assigned to
this port. Highlight COM 4 by clicking once on its listing in device manager, then
click Remove. Click Refresh. If the COM 4 listing returns, you have a hardware
device using the port. Reinstall the device on another COM port.
For Windows NT 4.0 Installation
Before installing your new modem, be sure to remove any modems and their drivers
from your operating system. On the taskbar, click Start. On the Start menu click
Settings, then click Control Panel. Double-click the Modems icon. Highlight the
modem you wish to remove and click Remove. Turn off the computer and physically
remove the old modem. Do not install your new modem at this time. Follow the
procedures below to help insure a trouble-free installation. Once you remove the old
modem and its drivers from your system, you will need the old modem driver diskette if
you wish to reinstall it at a later date.
Determine that your installation of NT 4.0 is current. Service Pack 3 (or greater),
from Microsoft, should be installed. On the Start menu, click Settings then click
Administrative Tools then click Windows NT Diagnostics. Select the Version folder.
Service Pack 3 (or greater) should be stated. If you do not have the latest service pack
upgrade installed, it must be obtained from Microsoft. The latest upgrade can be
downloaded from the Microsoft web site: www.microsoft.com.

Installing The Modem
Always discharge static electricity before handling your modem. You
may discharge static electricity by touching a grounded metal structure
or by using any commercially available grounding strap.
Make sure the expansion slot type is 16-bit, which has two slots to fit
the ISA card. 8-bit slots have only one connector. If you use an 8-bit
slot, the modem will not have access to the higher interrupts (IRQ 9-
12).
The position of the expansion slots in your computer may differ from
the illustration shown but the installation procedure should be the same.
Hardware Installation
1. Turn off the computer and all peripheral devices connected to it.
2. Unplug the computer power cord from the wall receptacle.
3. Remove the computer’s cover. Refer to your computer owner’s manual for in-
structions.
4. Remove the screw securing the expansion slot cover behind one of the computer’s
available PCI expansion slots. Lift the expansion slot cover out as shown below.

Installing Communications Software
If your modem came with a communications software package, it is strongly recom-
mended that you use this software for your modem. Its default installation param-
eters have been specially configured to work with this modem. The Users Guide for
this program can be found in Adobe Acrobat (PDF) format on the installation CD-
ROM.
Some configurations are packaged without communications software. Check your
packaging to see if communications software is included.
If you wish to use another software package, please be sure that it supports this mo-
dem. Most Software Manufacturers have a listing of supported modems on their
websites or BBSs. Check these sites to see if this model is supported. If you are unsure
or your brand of software supports only a few modems, try selecting “Hayes Com-
patible” or “Standard Modem”. This may work in certain cases.
Some software programs allow manual input of parameters. For the users of these
programs, here is a listing of the Data/Fax/Voice Command Standards supported.
Data:
TIA/EIA-602
Fax:
Voice:
Init String:
TIA/EIA-578 for Class 1 Fax
TIA IS-101 support for TAD (Telephone Answering Device)
AT&F&C1&D2W2
TIA IS-101 Commands not supported:
Caller ID
Full Duplex Speakerphone
VoiceView
Note: some programs must be configured to communicate with the modem on
the same COM port and or IRQ setting used by the modem. See the “In-
stalling the Modem” for instructions on how to determine your COM port
and IRQ settings.
The Modem’s Voice Features
This modem supports TIA IS-101 commands applicable to a Telephone Answering
Device. In order to take advantage of this feature, you will need a Sound Blaster®
compatible sound card equipped with an external microphone and external speakers.
A software application which supports these TAD functions (such as the one sup-
plied with the modem) is also required.
29
Download from Www.Somanuals.com. All Manuals Search And Download.
A modem basedTelephone Answering Machine works by using a sound card equipped
with a microphone to record an outgoing message. This message is stored as a .wav
file which is transferred to the modem by the application program when an incoming
call is detected. The modem’s internal electronics converts the digital information
contained in the .wav file into an audio signal which is then sent over the phone line.
The person calling hears your outgoing message and responds with an incoming
message.
The sequence of recording an incoming message is the reverse of an outgoing mes-
sage. The modem converts the audio signal into a digital format and sends it to the
application program. The application program then formats and stores the incoming
message as a .wav file. When you play back your stored messages by selecting them
from within the application program, they are sent to the sound card. You then hear
your recorded messages through the sound card’s speakers.
The default parameters of the software which came with your modem have been
specially configured to identify and use your modems voice capabilities. Even if you
have decided to use another third-party application, try your included application
first. This will allow you to test the modem and its voice functions before investing in
an expensive retail software package.

Troubleshooting
This section lists some common problems and offers suggestions for a solution. It is
important to remember that this modem is a Windows-based modem and requires
32bit virtual device drivers. It therefore cannot work in Windows 3.1 which cannot
use these drivers. The modem also cannot work in DOS regardless of version. It is a
software installed device and has no provisions for manual configuration.
If you cannot find your particular symptom listed here, it is suggested that you re-
move the modem and its drivers from the system and reinstall them again. (See
“Uninstalling the Modem” later in this section.) This provides a “clean” installation
and can cure many temporary problems. See “Do This First” for before reinstalling
the modem.
Most problems encountered during the Windows 95/98/NT installation process are
a result of insufficient system preparation. Make sure to physically remove any previ-
ously installed modems from your system.
If your modem has installed but is not functioning, try the troubleshooting proce-
dure listed below.
Windows 95/95B/98
Step 1: Check System Resources
On the taskbar, click Start. On the Start menu, click Settings, then click Control
Panels, and double-click the System icon. Select the Device Manager tab. From the
device tree, double-click the Modems icon to show what modems are installed. If
there is no Modems icon, your modem did not install (See “Does Not Install”.) If
your modem is listed, check that there is no yellow exclamation mark or red “X” over
the modem’s icon (if there is, go to step 2). If any other modems are listed, highlight
the modem by clicking once on the icon next to the listed modem and then click on
the Remove button. Turn off the system. Wait 5 seconds and turn your computer
back on and repeat step 1.
Step 2: Check Modem Properties
In the Device Manager tab of System Properties, double-click the Modems icon to
show what modems are installed. Highlight your modem by clicking once on the
icon and then click the Properties button. Read the Device Status under the General
tab to see if the device is working properly. Check the Device Usage area and make
sure “Disable in this hardware profile” (Windows 95B and 98 only) or the box la-
beled “Original Configuration, Current” has a check mark (for Windows 95 or 95A.)
31
Download from Www.Somanuals.com. All Manuals Search And Download.
If either of these conditions are present, correct them. Make a note of the Com port
and IRQ the modem is using. If the Device Status area shows some error message, it
will generally be about a conflict. Go to the Resources tab and read the Conflicting
Device List. If a conflict is present, click to deselect “Use automatic settings” and
select a configuration that does not cause conflicts. Manually change the IRQ set-
tings if needed (see your Windows 95 or 98 on-line help file for a more detailed
discussion on changing these settings). Click the OK button. If there is no setting
free of conflicts, See “Does Not Install.”
Step 3: Modem Diagnostics
On the taskbar, click Start. On the Start menu, click Settings, then click Control
Panel and double-click the Modems icon. Your modem should be listed. If any other
modem is listed, click once on each old modem and then click the Remove button. It
is a good idea to turn off your computer, wait 5 seconds and turn the power back on.
Return to Modems and click the Diagnostics tab. Highlight the modem by clicking
once on the COM port icon next to its listing. Now click the More Info button. You
should see the panel below.
Figure 8: More Info Panel
If you receive an error message or the panel is blank, see “Does Not Install” section.

Step 4: Does Not Install
The most likely reason for a non-installation in Windows 95 or 98 is a lack of IRQ
resources. The modem needs one IRQ and two I/O addressees in order to function.
Modern computer systems are usually equipped with sound card, CD-ROM drive,
Hard-drive, floppy drive, video card, two COM Ports, one LPT port, keyboard, and
a mouse. Each of these devices require at least one IRQ (interrupt) in order to func-
tion.
This section deals with the process of freeing IRQ’s and configuring the system for
Plug-N-Play requiring that you know how to enter your computer system’s BIOS
Setup Routine (read your computer user’s manual for information on how to invoke
and use the BIOS setup).
Once inside the BIOS Setup, find the Plug-N-Play configuration. This can be found
within the “Advanced”, “PNP/PCI Configuration”, or “Plug and Play Configura-
tion” section depending on the BIOS Manufacturer. Next, from the information you
noted in Step 2. Find the interrupt selection for the IRQ your modem is using.
(Some BIOSs do not allow individual selection of interrupts to ISA, Plug-N-Play, or
PCI.) You want to set this so that the PCI bus has access to this interrupt. This can be
called ICU/PCI, PCI, or PNP depending on your BIOS version and manufacturer.
Do not set this interrupt to “ISA” only or to “Legacy ISA”.
If you do not have any free interrupts available, you will have to disable some unused
function of your computer system. If you are using a PS/2 style mouse, you may be
able to spare one of your internal COM ports. To disable a COM port, find the
BIOS Setup section for “Integrated Peripherals”. Locate the Serial Port settings and
disable an unused port that has nothing connected to it This will often be serial port
2. This should free one IRQ for your modem to use. You may also have to disable the
COM Port in Windows.
Although it is possible for a PCI card to share interrupts, it is recommended that you
have one free IRQ available in your computer. The modem needs one IRQ and two
I/O Addresses to function. To check for any available interrupts in your system,
right-click on the My Computer icon, choose Properties, and select the Device Man-
ager tab. Click the Properties button to view the System Resources.
Their are 16 (0-15) interrupts available in a system. Make a note of any interrupt not
listed. To make sure that an available interrupt is assigned to the PCI bus, go to your
system BIOS Setup routine and find the Plug-N-Play settings. These are found in the
“Advanced”, “PNP/PCI Configuration”, or “Plug and Play Configuration” sections
depending on the BIOS Manufacturer.
Next, verify that one free IRQ has been set so that the PCI bus has access to it. (Some
33

BIOSs don’t allow individual selection of interrupts for ISA, Plug-N-Play, or PCI.)
The interrupt settings can be called “ICU”, “ICU/PCI”, “PCI”, or “PNP depending
on your BIOS version and manufacturer. Do not set this interrupt to “ISA” only or
to “Legacy ISA”. Be sure to Save the settings before exiting the BIOS Setup.
Under some situations, you will find that freeing an interrupt does not solve your
installation difficulties. This could be due to another peripheral device stealing the
interrupt you just provided. Certain full-featured sound cards require three IRQs to
support all their functions. When one becomes available, they take it. This situation
requires that you remove your sound card, free an interrupt, install the modem and
verify its operation, and then reinstall the sound card. This procedure may also work
for sound cards that have lost their sound after the modem has been installed or if the
modem will not install in a system with a sound card.
Proceed to “Installing the Modem”.
Windows NT 4.0
Windows NT installation problems are always due to inadequate preparation. The
following conditions must be meet before attempting to install the modem or it will
not be seen or correctly installed by the system. (See “Do This First” at the beginning
of this manual.)
•
•
You must have the latest Windows NT Service Pack installed.
There must be two IRQ and two I/O port Addresses available for the modem to
use.
•
The installation utility must be copied from the installation CD-ROM to the
default hard drive and extracted.
If you need help on freeing an interrupt or making a COM Port available, see the
Windows 95/98 “Does Not Install” section for a discussion of this topic. The “Spe-
cial Situations” and “Plug-N-Play BIOS” sections also apply to Windows NT 4.0.
See these areas for guidelines. If you are upgrading or removing the drivers, use the
installation utility on the Windows NT installation diskette that came with your PCI
modem. This utility has an option for removing the modem drivers.
If you are not familiar with changing the settings within your system BIOS setup,
you should skip the following system pre-installation procedure and go to “Installing
the Modem.” Refer back to this area only if you have a problem installing the mo-
dem.
Check your system BIOS IRQ assignments and make sure that at least two interrupts
have been assigned to the PCI bus. In your system’s BIOS Setup routine, find the
34

Plug-N-Play settings. These settings can be found within the “Advanced,” “PNP/
PCI Configuration,” or “Plug-and-Play Configuration” sections depending on the
BIOS Manufacturer. Next, verify that at least two IRQs have been set so that the PCI
bus has access to them (some BIOS don’t allow individual selection of interrupts to
ISA, Plug-N-Play, or PCI). These settings can be called ICU, ICU/PCI, PCI, or
PNP depending on your BIOS version and manufacturer. Do not set all the inter-
rupts to “ISA” only or to “Legacy ISA”. Pay attention to the IRQ usage of the other
peripherals in your system. Do not reassign an interrupt that is already in use by an
ISA card to the PCI bus.
Common Problems
No Dialtone Error
Make sure you have connected the phone cable into the right connector on the back
of the modem. See Figure 7.
You may have too many devices connected to the phone line. Remove all other equip-
ment.
Your modem may not recognize overseas dialtone. Use the AT command ATX0to
have the modem ignore (not look for) the dialtone before dialing. (See Appendix A
for information on how to use AT commands.)
Communications Software Does Not Work
Some communications software packages need to be configured to the same COM
port and or IRQ as the modem. See the “Installing the Modem” for information on
how you determine your COM Port and IRQ number.
Does the communications software support this modem? See the Installing and Con-
figuring Communications Software section.
If you are using a different software from the one supplied with the modem (some
models of this modem may be shipped without communications software), try in-
stalling the supplied software and verify its functionality with the modem.
Nothing Appears OnThe Screen When IType
Issue the AT command ATE1to the modem to enable command echo. This will let
you see what you type.

Can’t Connect at 56K
Note: Current FCC regulations limit your maximum connection rate to 53Kbits / s.
The number you are calling may not support V.90 or K56flex protocols. Some ISPs
(Internet Service Provider) have special numbers that you must call to connect to
56K. Contact your service provider and ask if the number you are calling supports
V.90 or K56flex connections to their service.
Check the maximum speed setting in the Modem Properties window. On the task-
bar, click Start. On the Start menu, click Settings, then click Control Panels. Double-
click the Modems icon. Highlight your modem by clicking once on the icon next to
the modem and then click the Properties button. Select the General tab and look at
the setting in the Maximum speed box. Make sure this is set to 115200.
You may have other telephone devices connected to the phone line. To help your
modem achieve the best connection possible, remove all extra devices and their cables
from the telephone line when the modem is in use. This reduces the load on your
phone line and keeps signal attenuation to a minimum.
Keep the length of your phone line cable to 10 feet or less. Don’t use an unusually
long cable to connect to the phone line socket. If necessary, move the computer
closer to the phone socket. Don’t lay your cabling close to an electrical appliance like
a refrigerator or air conditioner unit. High current devices can transmit a 60 cycle
“hum” to your modem through the phone cord. This may cause frequent renegotia-
tions or line disconnects while the appliance is running.
The telephone line conditions at the time of your call may not let you connect at
56K. The modem has a connection sequence of K56flex, then V.90, then V.34, and
so on. The modem attempts to make the highest connect rate that your telephone
line can support at the time of negotiation. If the line conditions (noise, telephone
company routing, etc.) won’t allow a high data rate connection, then the modem will
automatically connect at the most reliable rate. Try making the call again after a few
minutes. The routing of the call may improve your chances of making a 56K connec-
tion.
If you are attempting to make a call from an office, are you using a direct outside line
or are you using a PBX hookup? If you have to dial “9” to reach an outside number,
you are using a PBX. The modem cannot connect faster then V.34 if you are using a
PBX. Try using the line that is connected to a fax machine. Fax machines are usually
connected to a dedicated line and not through the PBX.
Your phone line may not support a 56K connection. Or may support a 56K connec-
tion only intermittently. There are many conditions that must be met before a 56K
36

connection can be established. The telephone company must have you connected to
the PSTN (Public Switched Telephone Network) in a particular way. The modem
you are calling must support the same protocol. The phone line must be free of
distortion and noise. The phone wiring in your house or building must be in good
condition and so on. Check to see if you have good voice communications while
talking to friends or relatives. Do their voices sound distorted? Do you hear a “hiss-
ing” or “humming” sound in the background? Is there “popping” or “crackling” dur-
ing your call? These are phone line problems. In the case of distortion, your phone
line is bad. Humming may be due to the cabling inside your residence coming too
close to a high current appliance or you may have a cordless phone recharger base
connected to the phone line. Popping or crackling usually indicates a loose connec-
tion to the outside line or water dripping on the hookup outside your house.
The drivers for your modem are constantly being refined to address problems with
compatibility, interoperability, and performance. Check the Actiontec website on a
regular basis for driver upgrades. A problem connecting to a particular provider might
be fixed by a simple software upgrade.
Uninstalling the Modem
If you are uninstalling the modem in Windows 95 or 98 in order to upgrade your
drivers or obtain a clean reinstallation, it is important to follow these directions care-
fully.
When removing the drivers from a system running Windows NT, use the installation
utility. The utility has an option to remove your modem drivers.
Uninstalling in Windows 95 and 98
Step 1 On the desktop, right-click the My Computer icon and choose Properties
from the menu that appears. Select the Device Manager tab. Double-click
the Modems icon to expand the Modems section of the list. Highlight your
modem by clicking once on its icon, then click Remove.
Step 2 On the taskbar, click Start. On the Start menu, click Settings, then click
Control Panel and double-click the Modems icon. If your modem is listed,
highlight the modem by clicking once on the icon next to the modem and
then click the Remove button. Or, if the New Hardware dialog box comes
up, click Cancel.
Your modem should not be listed in the Modems section after you have
deleted it from the Device Manager. This could be a sign that your Plug-N-
Play settings are not correct. See “Does Not Install” for more information
about Plug-N-Play.

ltdsvd.dll
ltports.inf
If you cannot find a particular file, it usually means it was not installed. After all
instances of these files have been deleted, restart your system.
Note to users of Windows 95 and 98
If you are using Windows 95B (see “Do This First” for instructions on how to deter-
mine your Windows 95 version), you need only delete the files listed. In the case of
Windows 95 or Windows 95A, there are two additional files which Windows 95 or
Windows 95A generates when installing a third-party hardware peripheral. The file
is called oem#.inf. The number (#) used is generated by Windows 95 each time
an additional piece of hardware is installed. In the case of the modem, these files
could have any number between 1 and 99--oem8.inf, for example.
Close all open windows and return to the desktop. On the taskbar, click Start. On
the Start menu, click Find, then click Files or Folders. Type in *.infin the Named
box. Make sure your entire drive is selected and not just one subdirectory. Place a
check mark in the Include subfolders box. Be sure all the information is typed in as
shown below. Before beginning the search, click the Advanced tab.

AT Command Set
AT Commands
AT commands are issued to the modem to control the modem’s operation and soft-
ware configuration. AT commands are commonly entered from a terminal program
such as HyperTerminal, and can only be entered while the modem is in command
mode. To enter an AT command, type:
ATXn
where X is the AT command, and n is the specific value for that command. Press
ENTER.
Commands are acknowledged with either text or numeric value response known as a
result code. In the case of multiple AT commands on the same command line, the
commands are executed in the order they are received. Should execution of a com-
mand result in an error, or a character not be recognized as a valid command, execu-
tion is terminated, the remainder of the command line is ignored, and the ERROR
result code is issued. If all commands execute correctly, only the result code associ-
ated with the last command shall be issued, even though all have been executed.
In the following listing all commands and command values accepted by the modem
are shown. Any entries other than those shown cause the ERROR result code.
+++
Escape sequence
The escape sequence allows the modem to exit data mode and enter on-line com-
mand mode. While in on-line command mode, you may communicate directly to
your modem using AT commands. Once you are finished, you may return to data
mode using the ATO command. A pause, the length of which is set by the Escape
Guard Time S-Register (S12--See the “S-Registers Reference” section of this manual
for details), must be used after an escape sequence is issued. This pause prevents the
modem from interpreting the escape sequence as data. The value of the escape se-
quence character may be changed using Register S2.
A/
Repeat Last Command
This command repeats the last command string entered. Do not precede this com-
mand with an AT prefix or conclude it by pressing Enter.

Dn
Dial
This command instructs the modem to begin the dialing sequence. The dial string
(n, including modifiers and the telephone number) is entered after the ATD com-
mand.
A dial string can be up to 40 characters long. Any digit or symbol (0-9, *, #, A, B, C,
D) may be dialed as touch-tone digits. Characters such as spaces, hyphens, and pa-
rentheses do not count, they are ignored by the modem and may be included in the
dial string to enhance readability.
The following characters may be used as dial string modifiers:
Redials last number. Should be the first character following
ATD, ignored otherwise. The modem displays the dialing string
in the following format: Dialingꢀxxxxxxx where xxxxxxx is the
L
last number dialed.
P

before processing the next character in the dial string.
Wait for dial tone. Modem waits for a second dial tone before
processing the dial string.
W
Wait for quiet answer. Wait for five seconds of silence after
dialing the number. If silence is not detected, the modem sends
a NO ANSWER result code back to the user.
@

S-Registers Reference
S-registers generally affect how the AT commands perform. Contents of the registers
can be displayed or modified when the modem is in command mode.
To display the value of an S-register:
TYPE:
ATSn?
where n is the register number. Press ENTER.
To modify the value of an S-register:
TYPE:
ATSn = r
where n is the register number, and r is the new register value. Press ENTER.
S0
Auto Answer Ring Number
Range:
Default:
Units:
0−255
0
rings
This register determines the number of rings the modem will count before automati-
cally answering a call. Enter 0 (zero) if you do not want the modem to automatically
answer at all. When disabled, the modem can only answer with an ATA command.
S1
Ring Counter
Range:
Default:
Units:
0−255
0
rings
This register, Ring Counter, is read only. The value of S1 is incremented with each
ring. If no rings occur over a six second interval, this register is cleared.
S2
AT Escape Character (user defined)
Range:
Default:
Units:
0−255
43
ASCII
This register determines the ASCII valued used for an escape sequence. The default is
the + character. The escape sequence allows the modem to exit data mode and enter
command mode when on-line. Values greater than 127 disable the escape sequence.
67

S3
Command Line Termination Character (user defined)
Range:
Default:
Units:
0−127, ASCII decimal
13 (carriage return)
ASCII
This register determines the ASCII values as the carriage return character. This char-
acter is used to end command lines and result codes.
S4
Response Formatting Character (user defined)
Range:
Default:
Units:
0−127, ASCII decimal
10 (line feed)
ASCII
This register determines the ASCII value used as the line feed character. The modem
uses a line feed character in command mode when it responds to the computer.
S5
Command Line Editing Character (user defined)
Range:
Default:
Units:
0−32, 127
8 (backspace)
ASCII
This register sets the character recognized as a backspace and pertains to asynchro-
nous only. The modem will not recognize the backspace 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
backspace character, an ASCII space character, and a second backspace character.
This means a total of three characters are transmitted each time the modem processes
the backspace character.
S6
Wait Before Dialing
Range:
Default:
Units:
2-65
2
seconds
This register sets the length of time, in seconds, that the modem must wait (pause)
after going off-hook before dialing the first digit of the telephone number. The mo-
dem always pauses for a minimum of two seconds, even if the value of S6 is less than
two seconds. The wait for dial tone call progress feature (W dial modifier in the dial
string) will override the value in register S6. This operation, however, may be affected
by some ATX options according to country restrictions.

S7
Connection Completion Time-Out
Range:
Default:
Units:
1-255
50
seconds
This register sets the time, in seconds, that the modem must wait before hanging up
because carrier is not detected. The timer is started when the modem finishes dialing
(originate), or goes off-hook (answer). In originate mode, the timer is reset upon
detection of an answer tone if allowed by country restriction. The timer also specifies
the wait for silence time for the @ dial modifier in seconds. S7 is not associated with
the W dial modifier.
S8
Comma Dial Modifier Time
Range:
Default:
Units:
0-65
2
seconds
This register sets the time, in seconds, that the modem must pause when it encoun-
ters a comma (“,”) in the dial command string.
S10
Automatic Disconnect Delay
Range:
Default:
Units:
1-254
20
0.1 seconds
This register 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. The actual interval the modem waits
before disconnecting is the value in register S10.
S11
DTMF Dialing Speed
Range:
Default:
Units:
50-150
95
0.001 seconds
This register determines the dialing speed which is prefixed for each country.
S12
Escape Guard Time
Range:
Default:
Units:
0-255

This command displays the number of seconds of inactivity (no characters sent from
the DTE, no RING) in the off-line command state before the modem places itself
into standby mode. A value of zero prevents standby mode.
If a number between 1 and 4 is entered for this register, it will set the value to 5, and
the inactivity before standby will be 5 seconds. This is done for compatibility with
previous products which allowed time-outs down to 1s.

FCC Regulations
The following statements are provided in accordance with the Federal Communica-
tions Commission (FCC) regulations. Please read these statements carefully before
installing your modem.
FCC Part 68 Requirements
This equipment complies with Part 68 of the FCC Rules. On the bottom of this
equipment is a label that contains, among other information, the FCC Registration
Number and Ringer Equivalence Number (REN) for this equipment. If requested,
this information must be given to the telephone company.
The REN is used to determine the maximum number of devices connected to your

areas, the total REN of devices connected to a line should not exceed five (5.0). To
find out the total permitted in your area, contact your local telephone company.
If your telephone equipment causes harm to the telephone network, the telephone
company can discontinue your service temporarily. If possible, the company will
notify you in advance. But if advance notice isn’t practical, you will be notified as
soon as possible. You will be informed of your right to file a complaint with the FCC.
Your telephone company can make changes in its facilities, equipment, operations,
or procedures that could affect the operation of your equipment. If so, you will be
notified in advance so you can make the changes needed to maintain uninterrupted
service.
If you experience trouble with this equipment, please contact the manufacturer at the

PRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR
COMPLIANCE COULD VOID THE USER’S AUTHORITY TO
OPERATE THE EQUIPMENT.
Canadian Department Of Communications (CDOC)
Requirements for End Users:
Notice: The Canadian Department of Communications label identifies certified equip-
ment. This certification means the equipment meets certain telecommunications
network requirements. The Department does not guarantee the equipment will op-
erate to the user’s satisfaction.
Before installing this equipment users should ensure that connection to the line is
allowed by the local telecommunications company. The equipment must also be in-
stalled using an acceptable method of connection. In some cases, the company’s in-
side wiring associated with a single line individual service may be extended by means
of a telephone extension cord. Compliance with the above conditions may not pre-
vent degradation of service in certain situations.
Repairs to certified equipment should be made by an authorized Canadian mainte-
nance facility designated by the supplier. Any repairs or alterations made by the user
to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines, and internal metallic water pipe system, if present,
are connected together. This precaution may be particularly important in rural areas.
