Installing the Modem’s Communications Software
The modem’s CD describes the communications software package
and online service included with your modem and provides easy
point-and-click installation. If necessary, consult the CD’s online help.
Please run the modem’s CD now. You should not install the drivers
again, but you should install any application software you like.
If you have a V.92 modem, after you’ve installed the CD software,
you should read the Important Information about V.92 Modems
section of this manual on page 7. Enjoy your modem.

Installing Your USB Faxmodem 7
Important Information about V.92 Modems
If you have a V.92 Modem
With V.92, as with the earlier V.90 standard, your connection speed
depends on your phone line and your Internet Service Provider (ISP).
To enhance compatibility, the V.92 modem automatically detects
whether to use V.92, V.90, or a slower mode when it connects to
your ISP.
Your V.92 modem includes the following capabilities.
•QuickConnect:
A V.92 modem remembers the line conditions of the last number
called, and uses this information to try to reduce connection
times.
•Modem-on-Hold:
You have the option of receiving voice calls while online. You can
answer the call and put your Internet session on hold if your ISP
supports this capability and you have Call Waiting service com-
patible with the modem. See page 8 for more details about Mo-
dem-on-Hold.
•Faster Upload Speeds:
Upload speeds may be increased, from 33.6K bps to a maximum
of 48K bps. (Actual rates vary, depending on line
conditions.)
•V.44 Data Compression:
The V.44 standard lets you browse the Web and transfer data at
higher speeds.
To make the most of your V.92 modem, follow these steps:
1. Contact your ISP and get the phone number of a V.92 connec-
tion to the ISP.
2. Check the modem's Web site for news of any V.92 updates. If an
update is available, follow the directions below for upgrading your
modem.

8 USB Faxmodem Installation Guide
Note: If you want to manually change the way your modem con-
nects, please consult the AT command tables beginning on
page 19 in the Troubleshooting section.
Modem Upgrades
Your modem’s software, or “firmware,” can be easily upgraded. This
is useful for code updates and feature enhancements. To upgrade
your modem’s firmware, you can download new firmware files, when
available, from our Web site, and then run a program we provide.
We also suggest that you register your modem with us so that we
can notify you via e-mail when new firmware releases are available.
How to Use NetWaiting Modem-on-Hold
Your V.92 modem includes the NetWaiting Modem-on-Hold program
from BVRP Software, which is compatible with all Windows operating
systems. This User Guide provides basic information on getting
started using the NetWaiting software. For more details, please refer
to NetWaiting’s built-in help.
Note: Your ISP must support the V.92 protocol; otherwise not all
Modem-on-Hold features will work. Contact your ISP if you are
unsure. Also, you must have Call Waiting/Caller ID (Type 2
Caller ID) service from your telephone company to use the
modem’s Call Waiting/Caller ID feature.
When you turn your computer back on after installing your modem
software and hardware, you will see NetWaiting’s yellow telephone
icon in your computer’s system tray. (If you do not see it, from the
desktop go to Start | Programs | NetWaiting, and then select Net-
Waiting to display the icon.) Tip: To avoid the step of re-activating
Modem-On-Hold every time you log on, right-click the system tray
icon and select Settings | Launch at Windows startup.

Installing Your USB Faxmodem 9
If someone calls while you are online, the NetWaiting box displays on
your computer screen, offering you three choices.
•Place your Internet connection on hold and accept the call (click
the OK icon).
•Reject the call and remain connected to the Internet (click the
red Xicon).
•Disconnect your Internet connection and accept the call (click the
Disconnect icon).
Note: The length of time that your modem can be on hold varies de-
pending on your ISP. Check with your provider.

stall and click Remove.
3Shut down your computer and unplug your modem.

Communicating with Your Modem 11
Communicating with Your Modem
The faxing and communications software that came with your fax-
modem sets itself up automatically and takes care of sending any
necessary commands to the modem.
You should read this section, however, if you want to learn some
general facts about how software works with your faxmodem, or if
you intend to use your new modem with other software.
Accessing the Internet
To access the Internet and the World Wide Web, you need an online
service such as America Online (AOL) or an Internet Service Pro-
vider (ISP). The best place to start is the CD included with your mo-
dem package, which contains online services for you to try.
Online services provide installation software that makes signing up
almost automatic. ISPs typically supply or suggest the browser soft-
ware needed to access their service. They also provide additional in-
structions and software for setting up your account.
Note: You may need to redirect your application software to recog-
nize your new modem; refer to page 15 if you need assistance.
Making the Most of the Fax Features
Your faxmodem includes software on the enclosed CD that enables
you to send, receive, and schedule faxes. The software will also let
you set up fax-back, sometimes called fax-on-demand, and issue fax
broadcasts.
If you use your modem for receiving faxes, keep in mind:
•Your computer must be running, and the communications soft-
ware must be active.

12 USB Faxmodem Installation Guide
•If you want to connect to your online service or ISP, you must exit
the communication software first. While you are on line and if you
do not have a V.92 modem model, you may not receive calls or
faxes.
•Some computers have a power saving option that stops the hard
drive from spinning after a period of inactivity. If a call comes in,
it may fail to connect while the hard drive restarts and activates
the software. If this happens, you should deactivate the feature
of your power saving option that stops the hard drive. See your
computer's documentation for details.
Communication Setup Options
If you run into configuration difficulties with your communication soft-
ware, it may be helpful to read the following section.
In setting up some older software programs, you may be asked to
enter certain information. Most programs have default settings that
are correct for use with this modem, and there is no need to change
them. However, you should be aware of the following items:
If you are asked to select the “modem type” from a menu, and you
don’t see your modem listed by name, select the most descriptive
name such as V.92 modem, 56K modem, or generic Class 1 Mo-
dem.
In the dialing directory, set all entries to the highest possible baud
rate, if your software and serial port support these speeds (do not go
over 115,200 bps). All communications between the computer and
the faxmodem take place at this higher speed, independent of the
modem-to-modem speed.
If your fax software gives you the option of selecting Class 1 or
Class 2 fax drivers, select Class 1.

Communicating with Your Modem 13
Initialization Strings and AT Commands
An initialization string is a group of AT command settings that is sent
to the faxmodem as soon as you start up the software. The software
determines which commands should be included in the initialization
string, based on the device you select during installation. The com-
mands remain in effect throughout the communications session, un-
less the software sends other commands to override them.
The software uses other AT command strings for all commands sent
to the modem. This is transparent to you—the software does this in
the background without you being aware of it.
It is sometimes necessary, however, to add other AT commands to
initialization strings. You can find a table of AT commands on the
World Wide Web at www.modems.com. Click Reference and then
on AT Command Sets.
If your software suggests an initialization string for this modem, you
should use it. If your software does not list this modem and no initiali-
zation string is suggested, use the following: AT &F.
Your telephone service may include Call Waiting that you can tempo-
rarily suspend by using your phone to dial a special code. (For ex-
ample, in the U.S., you can disable call waiting by adding *70 to your
dialing prefix; please check with your local phone company for the
correct code for your area.) You can include that code, followed by a
comma, in the dial string or dial prefix in your software.
If your software does not handle AT commands automatically, it
should provide a place to enter AT commands in its setup menus.
However, in some cases you may need to enter AT commands di-
rectly to the faxmodem. You must do so from a data program’s ter-
minal mode.
Refer to the Troubleshooting section for more tips about AT com-
mands.
Using Terminal Mode to Enter AT Commands
Start your data communications program.

14 USB Faxmodem Installation Guide
Change to terminal mode (also called command, local, direct, or
dumb mode). Check your software documentation for additional in-
structions.
Type AT plus the command you need and press Enter. You will see
an OK response.
When you finish, you can return to the data communications pro-
gram’s standard user interface. See the software program’s docu-
mentation if you need help.
To return to the factory default settings for the modem, in terminal
mode, type AT &F and press Enter.
Using Video
Your faxmodem supports video applications through the V.80 stan-
dard protocol so that it can be used for high-quality modem-to-
modem videoconferencing. The modem is compatible with H.324
point-to-point and H.323 Internet video conferencing standards. To
send videos, you need a camera and video software.

Troubleshooting 15
Troubleshooting
If your modem stops working, please read this section carefully be-
fore calling Customer Support. In addition, your modem CD includes
a list of Frequently Asked Questions (FAQs).
Important—If Your Computer Had an Existing Modem
You must redirect your application software so that it recognizes your
new modem.
•America Online Users: From the AOL Welcome screen, click the
Setup button; then click Expert Setup. Select the Devices tab
and double-click the name of your new modem.
•Dial-up Networking Users: From your computer’s desktop,
double-click My Computer and then Dial-up Networking. Dou-
ble-click the Make New Connection icon, select your new mo-
dem from the dropdown list, and follow the prompts.
Plug and Play Setup Problems with Windows
Under some circumstances, the Plug and Play setup under Windows
may not resolve all installation problems. The Windows Help system
has a tool for thoroughly diagnosing and solving many problems, in-
cluding hardware conflicts.
1. On your desktop, double-click the My Computer icon.
2. Choose the Help Topics command in the Help menu. Win-
dows displays the Windows Help dialog box.
3. Select the Contents tab. Note: Windows Me and 2000 include
a Help Search option, which you can use instead; search for
“hardware conflict,” for example.
4. Click Troubleshooting. (For Windows 98, you will also have
to click Windows 98 Troubleshooters.) Then click the
Hardware Conflict help entry.

16 USB Faxmodem Installation Guide
5. Follow the instructions for determining and resolving a hard-
ware conflict.
This should solve your problem. Remember to write down your COM
port setting.
Other Troubleshooting Tips
Problem:Your modem seems to install under Windows, but
Windows cannot find it later.
Solution:If your computer has a built-in modem on the mother-
board, Windows may reinstall it the next time you start
up. Consult your computer’s documentation or call your
computer’s manufacturer to get instructions on how to
disable the built-in modem.
Problem: The software cannot find the modem and the modem
does not respond to AT commands. (The following
comment applies to many other problems as well.)
Solution:The most common problem with modems is that the
communications software is not configured for the same
port as the modem.
Check which port the modem is using. Make sure that
the software’s COM port setting matches the modem’s
COM port setting.
From the Windows toolbar, go to Start | Settings | Con-
trol Panel | Modems | Diagnostics. Click the COM
port for your modem, then click More info. If Windows
displays the modem’s ATI responses, the modem is
working.
Another problem is that COM port resources may be in
use by another device. Make sure that the COM port re-
sources used by the modem are not being used by any
other device, such as a soundcard.

Troubleshooting 17
Problem:You type an AT command line in a terminal applica-
tion and press Enter, but your modem fails to exe-
cute the command line. Or there was no response af-
ter executing a command.
Solution:Be sure you type AT at the beginning of the command
line.
If you type more than one AT command, type a semico-
lon (;) immediately after each one.
Make sure the communications software is configured
for the same COM port as your modem.
Be sure your modem is not in data mode when you type
the command. Use the escape character sequence to
switch to terminal mode (The default escape sequence
is to wait at least one second, type +++, and wait another
second or more.)
If you typed a command but did not receive an OK re-
sponse from your modem, the E0 and Q1 commands
may be in effect, disabling echo and responses. Verify
this with the &V command. To enable echo and re-
sponses, type ATE1Q0 and press Enter.
Problem:The modem speaker volume is too low or too high.
Solution: Your modem has a small speaker on board that provides
audible feedback of dial tones and remote connection
signals (“handshaking”). This is not the same as the
speaker that you may have connected to your sound
card.
If the software allows you to control the volume, make
sure the speaker is enabled and set to a comfortable
volume.
If the software does not have speaker settings, add one
of the AT commands listed below to the initialization
string:

18 USB Faxmodem Installation Guide
L1 for low volume
L2 for medium volume
L3 for highest volume
M0 to turn the speaker off entirely
For example, if you want the volume low and the soft-
ware uses the initialization string
AT &F, change it to AT &F L1.
Problem:The modem can connect to some modems, but not
to others.
Solution:A remote modem does not respond because of the ex-
tended negotiation process by which modems determine
the best common connection between them. If this is the
case, you may have to disable part or all of the negotia-
tion process. If you are using Dial-up Networking (DUN),
you can do so from the Control Panel. Depending on
your operating system, go to Modems, Phone and Mo-
dem Options | Modems, or Printers and Other Hard-
ware. Click the Properties tab and then Advanced. Un-
der Extra Settings, you can enter Extra Initialization
Commands. Referring to the following table of com-
mands, try one command at a time, beginning with the
fastest possible speed, until you successfully make a
connection.
