Key Steps for Linux
You should have already installed your computer hardware.
Turn your computer back on.
You need to verify that your modem is configured and work-
ing properly by issuing an AT command. You’ll need to use a
data communications program such as Minicom, which
comes with most versions of Linux, or a similar alternative.
To use Minicom, you will need to know the serial port the
modem is connected to.
Consult your on-line LINUX-HOWTO Documentation if you
need assistance. The section Communicating with your
Faxmodem on page 16 contains additional information
about using your faxmodem.
Please continue reading the Important Information for
Owners of V.92 section of this manual on page 12.

12 Modem User Guide
Important Information for Owners of
V.92 Modems
With V.92, as with the earlier V.90 standard, your connection
speed will depend on your phone line and your Internet Service
Provider (ISP). To enhance compatibility, this modem automati-
cally detects whether to use V.92, V.90, or a slower mode when it
connects to your ISP.
•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 compatible with the modem.
•Faster Upload Speeds:
Upload speeds may be increased, from 33.6K bps to a
maximum of 48K bps. (Actual rates will 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 ask for the phone number of a V.92
connection to the ISP.
2. Check our web site for news of any V.92 updates. If an up-
date is available, follow the directions below for upgrading
your modem.

Firmware Upgrades 13
Modem Upgrades
Your modem’s software, or “firmware,” can be easily upgraded.
This is useful for code updates and feature upgrades. To up-
grade your modem’s firmware, you simply download the new
firmware files and then run a program we provide. Because V.92
technology is new, you may want to download the latest firmware
before calling your first V.92 site. Upgrades are available from
our Web site.
We also suggest that you register your modem with us so that we
can notify you via e-mail when new firmware releases are avail-
able.

16 Modem User Guide
Communicating with your Faxmodem
The faxing and communications software that came with your
faxmodem sets itself up automatically and takes care of sending
any necessary commands to the faxmodem.
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 faxmodem 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 CompuServe, or
an Internet Service Provider (ISP). The best place to start is the
CD(s) included with your modem package, which contains Inter-
net and online services for you to try.
Online services provide installation software that makes signing
up almost automatic. ISPs typically supply or suggest the
browser software needed to access their service. They also pro-
vide additional instructions and software for setting up your ac-
count.
Note: You may need to redirect your application software to rec-
ognize your new modem; refer to the Troubleshooting section,
page 19, if you need assistance.
Communication Setup Options
If you run into configuration difficulties with your communication
software, 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 this modem listed by name, select the most de-

Communicating with your Faxmodem 17
scriptive name such as V.92 modem, 56K modem, or generic
Class 1 Modem.
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 there is a section of your software called “Terminal Settings,”
make sure that Hardware Flow Control (RTS/CTS is ON (or
YES).
Set auto baud detect to OFF (or NO).
If your fax software gives you the option of selecting Class 1 or
Class 2 fax drivers, select Class 1.
Finally, some programs ask Send init if CD high?, which you
should set to YES. Otherwise, the faxmodem may not receive the
proper initialization string.
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 instal-
lation. The commands remain in effect throughout the communi-
cations session, unless 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 having to be 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 on Refer-
ence and then on AT Command Sets.

18 Modem User Guide
Here are two of the more useful commands:
If your software suggests an initialization string for this modem,
you should use it. If your software does not list this modem and
no initialization string is suggested, use the following: AT &F.
Your telephone service may include Call Waiting that you can
temporarily suspend by using your phone to dial a special code.
You can include that code, followed by a comma, in the dial
string or dial prefix in your software. Refer to the
Troubleshooting section for more tips.
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 directly to the faxmodem. You must do so from a
data program’s terminal mode.
Using Terminal Mode to Enter AT Commands
Start your data communications program.
Change to terminal mode (also called command, local, direct, or
dumb mode). Check your software documentation for additional
instructions.
Type AT plus the command you need and hit 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
documentation if you need help.
To return to the factory default settings for the modem, in termi-
nal mode, type AT &F and hit Enter.
