Using Your Modem
If you have installed the faxing and communications software that
came with your modem, you probably do not need to read this section. The software sets itself up automatically and takes care of
sending any necessary commands to the modem.
You may, however, want to read this section if you want to learn
some general facts about how software works with your modem or if
you intend to use your new modem with other software.
This section provides tips for setting up faxing and communications
software, sending initialization strings containing AT commands to
the modem, using a video camera, and accessing the Internet.
Using Fax/Data/Voice Communications Software
Fax and data communications programs are designed to simplify the
tasks of sending and receiving faxes and data. You communicate
with most programs by making menu selections. The programs then
translate your selections into the AT commands needed to communicate with the modem. In addition, your modem supports a fullfeatured single or multiple mailbox voicemail system. Through your
software, you can also set up fax-back (fax-on-demand), and record
and playback messages.
When you install your software, you are taken through a series of
setup options. With virtually all commercially available software, once
you select the name of your modem during installation you can accept all the default settings that the software suggests.
Customizing Modem Settings
The software sends a string of AT command settings to the modem
as soon as you start up the software. The string is called an initialization string. The software determines which commands go into the initialization string based on the device you select during installation.
Using Your Modem 11
The commands remain in effect throughout the communications
session, unless the software sends other commands to override
them.
The software uses other AT command strings for other purposes.
For example, when you make a call from your modem, the software
inserts AT commands in a dial string with the phone number you are
calling. You can use the AT command strings that are provided with
the software.
It is sometimes necessary, however, to add other AT commands to
initialization strings. Some AT commands are suggested in the following sections and in
discussion of AT commands on the World Wide Web at
www.modems.com
mand Sets
In setting up your software, you may be asked to enter certain information. Most programs have default settings that are correct for use
with this modem, and there will be no need to change them. You
should, however, check the following items.

When you use your software and modem, you will rarely, if ever,

want to enter AT commands, however, you must do so from the
software’s terminal mode.

The modem is in data mode when it is communicating online with
another modem, such as a modem at your workplace or home.

Hot Swapping the PC Card
Your PC Card modem hardware supports hot swapping (or “hot
plugging”). This means that after installing the modem you can remove and re-insert it as needed without powering down or restarting
(rebooting) your computer. If you are using Windows with PC Card
2.x-compliant card management software, hot swapping is supported
automatically.
Note:
For reliable communications, you should insert the modem
card before you start up your data communications or fax
software. Otherwise the modem will not receive the initialization string from the software. You should remove the modem
only after you exit the software or the modem may not receive important call termination information.
Conserving Power
To conserve power when the modem is running on the computer’s
battery, the PC Card defaults to sleep mode when not in use. When
the modem is in sleep mode, it “wakes up” as soon as it senses activity such as a modem command or an incoming call.

Disabling the Computer’s Sleep Mode When Using AutoAnswer
Many notebook computers also have a sleep mode. It is usually implemented by software that automatically shifts the computer to a reduced operating speed when the processor has been idle for more
than a specified period of time. If you want the modem to answer incoming data or fax calls when you are away from the computer, you
may need to disable the computer’s sleep mode. Refer to your computer’s documentation if you do not know how to do this. You should

Important V.92 Modem Information
If your PC Card modem is a V.92 model, you should read this section. 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 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 compatible
with the modem. For more information, turn to pages 18 and 19.
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 our web site for news of any V.92 updates. If an update is
available, follow the directions for upgrading your modem.
Important Information About V.92 Modems 17

use by another device. Make sure that the COM port resources used by the modem are not being used by any
other device, such as a soundcard.
:
You type an AT command line in a terminal application and press Enter, but your modem fails to execute the command line. Or there was no response after executing a command.
:
Be sure you type AT at the beginning of the command
line.
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.)
Troubleshooting 23
If you typed a command but did not receive an OK response 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 responses, type
ATE1Q0
and press
Enter

:
The modem speaker volume is too low or too high.
Your modem’s software may allow you to control the volume; if so, 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:
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 software uses the initialization string

:
Make sure the modem speaker is turned on in your software so that you can hear dialing sounds. Also, make
sure that the phone line is plugged in.
Make sure that you are dialing a valid phone number, including any required dial prefixes.
If you are using tone dialing on a line that requires pulse
dialing, the line may not be able to accept tone-dialed
calls. Select Pulse dialing in your software, or make sure
software dialing prefix is
ATDP
(for pulse dialing).
Make sure your communications software and modem
are configured for the same COM port.

terminal mode.
Problem
Solution
:
The modem can connect to some modems, but not
to others.
:
A remote modem does not respond because of the extended 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 negotiation process. In the following table, “protocol” means error correction and data compression.
Troubleshooting 25
To force different communication speeds Type these AT commands
and press Enter
Negotiate speed and protocol
(default setting)
To force protocol
Dualmode (V.90 or V.92)—56000 bps
V92 only (disable V.90)—56000 bps
V.90 only (disable V.92)—56000 bps

V.32—9600 bps
2400 bps
1200 bps
Notes:
Some software allows these commands to be added to the
list of dial prefixes or the initialization string.
When the protocol is forced, the modem will not attempt to
connect at other protocols if it cannot connect at the forced
protocol. It will try to connect at the fastest speed available
within the forced protocol.

There are other configurations that can be forced as well. If you need
to select a particular configuration, use the AT command strings

Solution:
First be sure that you have the latest modem firmware
downloaded from our Web site, as discussed on page

Problem: Your modem disconnects while communicating with
a remote system.
Solution:
The remote system has hung up, and you need to reconnect. The other most common sources of interruptions are Call Waiting or someone picking up an extension phone.
If you have Call Waiting, you can usually temporarily disable it by including
*70,
(including the comma), or by se-
lecting it as a prefix, in the software’s dialing directory.
Depending on your service, you may not be able to dis-
able Call Waiting for incoming calls. If your incoming
data calls are frequently disrupted by Call Waiting, you
should consider dropping the service or installing a separate phone line without Call Waiting.
28 PC Card User’s Guide
Problem: Your modem does not make a connection.
Solution:
If your modem places calls but never connects, make
sure you are dialing the right number and that the remote
modem is turned on.
Problem: You receive bursts of errors occasionally, but oth-
erwise data quality is good.
Solution:
The connection may have been established on poorquality or noisy telephone lines. Hang up and place the
call again to try to obtain a better connection.
Someone may be picking up an extension connected to
the line that your modem is using. If your modem is
sharing a telephone line with other telephones, inform
the other users when you will be making a data call, or
install a separate line dedicated to data calls.
Your telephone line may have a Call Waiting feature and
a call is being received. See the Call Waiting discussion
above.
Problem: Random errors occur or data is missing in transmit-
ted data.
Solution:
Use the MNP or V.42 protocol if the remote modem supports one of these protocols. See the tables in this Troubleshooting section for more information.
Select a lower baud rate in your communications software and place the call again.
If both modems are using the MNP or V.42 protocol, the
only way this can occur is if your modem and communications software are not using the appropriate flow control. Configure your communications software for
RTS/CTS
(hardware) flow control. Your computer will
now pause for the transmission to be stored.
Troubleshooting 29
Problem: Modem performance seems sluggish.
Solution:
If you are connected to the Internet, there may be a lot of
traffic at the Web sites you are visiting. Other possible
causes are lack of sufficient memory in your computer
(16 megabytes of RAM required) or a slow processor
(you need a Pentium
®
133 or faster, or equivalent).
Problem: Data appears garbled on the screen.
Solution:
Your communications software character set-up (start
bit, data bits, stop bits, and parity bit) does not match
that of the remote system. Compare the settings and
make sure they match. Pay particular attention to the
parity setting—this is the most common difference
among systems. You should normally use 8 data bits,
NO parity, and 1 stop bit (
8, NONE, 1
or
8N1
). Another
common setting is 7 data bits, EVEN parity, and 1 stop
7, EVEN, 1
bit (
or
7E1
).
Problem: You encounter communications problems with your
modem.
Solution:
Check that your communications software has been set
up properly. Recheck the initialization string and dial
string specified in your software manual.
Memory-resident programs can cause a variety of problems. Try starting up your computer without them. Programs that can cause problems include antivirus programs and screen savers.
Problem: You are using a Macintosh and when you switch
network locations or eject the PC card modem, you
receive the message that you must restart your
computer.
Solution:
This is a characteristic of Mac OS X. It has nothing to do
with your PC card modem. Apple resolved this conflict in
Mac OS X 10.2.
