Introduction 1-1
Chapter 1
The Courier
The Courier V.Everything Internal Modem makes any
IBM-compatible computer with an Industry Standard
Architecture (ISA) or Extended Industry Standard Architecture
(EISA) expansion bus capable of exchanging data with modems
or fax machines over standard, analog telephone lines at speeds
of up to 33.6 Kbps.
Using the Courier
The most common uses of the Courier modem are accessing the
Internet or online services, accessing corporate networks
remotely, calling bulletin board systems (BBSs), and for sending
or receiving facsimiles or files.
Using the Courier always requires some kind of
communications software. The software required differs
depending on what you’re trying to do.
Accessing the Internet
To access the Internet, you need to set up an account with an
Internet service provider in your area. Often, Internet service
providers supply you with the software you’ll need. In other
cases, support for Internet access is built in to your computer’s
operating system, as is the case with Windows 95.
The software needed to access the Internet is called a TCP/IP
protocol stack. Your TCP/IP protocol stack must provide a
dialing application that is capable of sending data over a serial
line using the Point-to-Point protocol (PPP) or the Serial Line
Internet Protocol (SLIP).

1-2 Courier V.Everything Internal Modems: Getting Started
Calling Online Services
Each online service, such as America Online or CompuServe,
provides its own customized communications software package.
A couple of these packages are included with the Courier. These
packages do the dialing and guide you through the steps of
registration.
Accessing Corporate Networks Remotely
Dialing in to a remote network requires remote access software.
When you dial in to a network, the software makes your remote
computer appear to the network as locally attached. You can
then use your network just as you would if you were there: send
mail, print files, and access LAN drives.
A remote access package is included with the Courier.
Calling Bulletin Board Systems (BBSs)
Calling a BBS requires communications software that does
terminal emulation. The software should also support common,
standard file transfer protocols, such as YMODEM and
ZMODEM.
A communications software package is included with the
Courier.
Sending Facsimiles or Files
Most communications software packages support file transfers
and many support fax operations. You can use fax-capable
software to call fax machines or other fax modems and send
facsimiles.

Features
33.6 Kbps Connectivity
The Courier contains software that enables 31.2 and 33.6 Kbps
connection rates, as well as improves throughput at lower
speeds. While line conditions may not always allow for
33.6 Kbps connections, the new software makes it more likely
that your Courier will achieve and maintain 28.8 Kbps
connections. It can add up to 4800 bps to the average V.34
connection rate.
Selective Reject
Selective Reject is an optional part of the ITU V.42 (LAPM)
specification. This feature improves performance on noisy lines
by reducing the amount of overhead incurred when the protocol
must resend data due to errors.
When selective reject is active, only the frame that contained the
error is resent, instead of the frame plus all of the following
unacknowledged frames. You can disable selective reject by
changing a setting in S-Register 51 (see Appendix A, Alphabetic
Command Summary, in the Courier Modems Command
Reference manual).
Attaining Speeds Above 28.8 Kbps
V.34 connections at 21.6, 24.0, and 26.4 Kbps are common. To
get connections of 28.8, 31.2, and 33.6 Kbps, line quality must be
pristine end-to-end. In addition, 31.2 and 33.6 Kbps connection
rates are possible only when the device to which you are
connecting also runs software that supports speeds above
28.8 Kbps.
If you are curious about the role that line quality plays in
attaining and maintaining high-speed connections, and want to
learn what you can do to improve connections, request the
following document from our Fax on Demand service: Phone
Line Quality and High Speed Connections. The Fax on Demand
number is [phone].

The Courier 1-5
V.Everything
The Courier provides full support of the V.34 standard, V.Fast
Class, V.32 terbo, and many other modulation schemes, spanning
the range of speeds between 33.6 Kbps and 300 bps. We call this
unique combination of abilities V.Everything. See the
Compatibility section in Appendix B, Technical Specifications, for
details.
Flash ROM Upgradability
Courier modems are software-upgradable using XMODEM file
transfers, allowing you quick, easy access to updates of the
Courier’s technology. See Chapter 17, Upgrading the Courier’s
Software, in the Courier Modems Command Reference manual.
Dial Security
The Courier’s dial security functionality is part of its operating
software, which allows you to control access at a modem-to-
modem level instead of using software that runs on the host
computer.
With Dial Security, you can prevent unauthorized access to a
system through the use of password prompting and dialback.
Refer to Chapter 9, Dial Security, in the Courier Modems Command
Reference manual.
Remote Configuration and Diagnostics
You can remotely configure and test the Courier. If you are a
network administrator supporting remote users, this feature can
save you time and money. Refer to Chapter 8, Remote Access, in
the Courier Modems Command Reference manual.
Adaptive Speed Leveling (ASL)
Couriers monitor line conditions while connected, and fall back
to the next lower speed—for example, 19.2K, then 16.8K in
V.32terbo mode—if conditions are poor. Couriers also detect
improved line conditions and shift upward to the next higher
speed. Transmit and receive channels adapt independently,
each detecting and adjusting to line conditions.

1-6 Courier V.Everything Internal Modems: Getting Started
Calls to and from Modems and Fax Machines
When used with fax-capable communications software, the
Courier auto-detects and responds to calls from modems and
Group III fax machines using EIA-standard Class 1 or 2.0 fax
software.
Testing
ITU-T V.54 loopback testing is available. The Courier can
perform analog, digital, and remote digital loopback tests. See
Chapter 15, Testing, in the Courier Modems Command Reference
manual.
Caller ID Support
The Courier can interpret and display caller ID information. See
the Caller ID section in Chapter 3, Dialing, Answering, and
Hanging Up, in the Courier Modems Command Reference manual.
Distinctive Ring Support
The Courier can be set to recognize and respond to any of four
distinctive ring patterns. See the Distinctive Ring section in
Chapter 3, Dialing, Answering, and Hanging Up in the Courier
Modems Command Reference manual.
Carrier Loss Redial
If you enable the carrier loss redial feature, the Courier will
automatically redial the last number it dialed if carrier is lost (for
example, if there is trouble on the line or if the remote modem
hangs up). This feature is useful for dialed-line connections that
operate unattended. See Chapter 3, Dialing, Answering, and
Hanging Up, in the Courier Modems Command Reference manual.
Plug and Play Support
When you install the Courier in a computer that uses a Plug and
Play operating system, such as Windows 95 or OS/2 Warp, the
computer will automatically detect and configure itself to the
support the Courier.

The Courier 1-7
Dedicated- and Leased-Line Support
The Courier does not need to be connected to the public
switched telephone network. You can connect a standard
telephone cable between the Courier and another modem and
make connections without even dialing. You can also connect
the Courier to a line that you lease from the telephone company.
See Chapter 12, Dedicated/Leased Line and Synchronous
Applications, in the Courier Modems Command Reference.

What You Need
You must have these before you start:
An IBM-Compatible Computer
Your computer must have an ISA or EISA expansion bus and an
available expansion slot. Check your computer’s user’s manual
to be sure.
An Analog Telephone Line
The Courier requires a standard, analog telephone line. Do not
connect the Courier to a digital telephone line! Digital lines are
commonly used in office buildings and hotels. If you are unsure
whether your line is analog or digital, ask a network
administrator or your local telephone company.
Communications Software
You must configure and run a communications software
package in order to make the Courier work. All Couriers are
shipped with a DOS/Windows communications software
package for your use.
Tools
A screwdriver that is appropriate for the screws in your PC.

Important!
The Courier emulates a serial interface card with a 16550 UART.
Like serial interface cards, it must be assigned a unique
communications (COM) port number and a unique interrupt
request (IRQ) number.
If you are using a computer with a Plug and Play compliant
BIOS and operating system, if you set the Courier’s jumpers to
Plug and Play, your computer’s operating system will take care
of the COM and IRQ settings for you.
Setting the COM port and IRQ yourself requires a detailed
knowledge of the settings of the other adapter cards in your

Installing the Courier 2-3
computer. If other adapter cards are set to use the same COM
port or IRQ, conflicts may occur that could result in data loss or
lock ups.
First, determine whether your computer has a Plug and Play ISA
bus. Check your computer’s documentation to be sure. Keep
these points about Plug and Play in mind:
♦Your computer’s Basic Input/Output System (BIOS) must
support Plug and Play, and
♦ Your computer’s operating system must support Plug &
Play (examples of those that do: OS/2 Warp, Windows 95,
Windows NT), or your computer’s manufacturer must
supply you with Plug and Play software.
If your computer has a Plug and Play ISA bus, BIOS, and
operating system, follow the steps in Plug and Play Setup. If not,
follow the steps in Standard Setup.

2-4 Courier V.Everything Internal Modems: Getting Started
Plug and Play Setup
The Courier is Plug and Play capable, but is shipped with
settings for COM2 and IRQ3. To prepare the Courier for
installation in a computer with a Plug and Play operating
system, locate the jumpers at the bottom corner of the card.
Figure 2-2. Location of the Jumpers.
1Remove the jumper from C. The positions of all other
jumpers, including the IRQ jumpers, are irrelevant while
Plug and Play is selected, and are ignored.
