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).

Introduction 1-1

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.

The Courier 1-3

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].

1-4 Courier V.Everything Internal Modems: Getting Started

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-to­modem 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.

The Courier 1-5

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.

1-6 Courier V.Everything Internal Modems: Getting Started

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.

The Courier 1-7

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.

Chapter 2

Installing the Courier

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.

Installing the Courier 2-1

Package Contents

♦ The Courier
♦ Phone cable
♦ Quick reference card
♦ Customer support services card
♦ DOS/Windows communications software package
♦ A Command Reference manual and this Getting Started

manual.

Figure 2-1. Contents of the Courier Package.

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

2-2 Courier V.Everything Internal Modems: Getting Started

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.

Installing the Courier 2-3

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.

Remove the jumper from C. The positions of all other

1

jumpers, including the IRQ jumpers, are irrelevant while
Plug and Play is selected, and are ignored.

The methods of verifying communication with the Courier vary
depending on the operating system your computer uses.

Windows 95 DOS
Windows 3.x OS/2
Windows NT Linux

This chapter provides advice about how to get many popular
operating systems to communicate with the Courier. The last
section, Testing the Courier, explains how to verify that your
Courier and software are working together correctly.

Windows 95

The first time you start Windows 95 after you’ve installed the
Courier, Windows 95 will auto-detect the Courier.

Windows 95 has built-in support for Couriers, but since the
Courier has been updated since the release of Windows 95, you
need to supply Windows 95 with an updated INF file so it can
properly identify your Courier. The latest INF file is always
available from our BBS and our ftp site.

Chapter 3

2

HyperTerminal, which is included with Windows 95) and
dial the U.S. Robotics BBS at [phone].

Go to File directories, then 5) U.S. Robotics Courier.
Download the MDMUSRCR.INF file.

Or, ftp://ftp.usr.com/SYS/PCB/dl05 and get MDMUSRCR.INF.

Installing the INF File

Go to an MS-DOS Prompt:

1

Microsoft® Windows 95

©Copyright Microsoft Corp 1981-1995

c:\WINDOWS>

Change to the directory in which you put the INF file; for

Windows NT

Determining COM Port, IRQ, and I/O Address Settings

Use WinMSD to determine which COM ports, IRQs, and I/O
base addresses are free.

Bear in mind that you can change the settings in Control Panel |
Ports | Advanced only if you have logged in to NT as
administrator.

As a Client

If you want only to dial out using the Courier, Windows NT
works very much like Windows 3.x. Windows NT ships with a
built-in Terminal program that can support speeds of up to 115.2
Kbps.

Additionally, Windows NT includes a Remote Access Dialer, but
it is not installed by default.

You can install Quick Link II in Windows NT but you may
experience problems with fax operations.

As a Server

Here’s how to set up Windows NT Remote Access Service (RAS)
to recognize the Courier. First, you must install RAS, which is
included with Windows NT, but is not installed by default.

Start Windows Terminal to verify that NT can communicate
with the Courier. Select the COM port to which the Courier is

Communicating with the Courier 3-9

connected. You should be able to send AT <Enter> and get an
OK response.

From the Control Panel, double-click Network. The Network
Settings window appears. Scroll down the list of Installed
Network Software and select Remote Access Service.

Click Configure… The Remote Access Setup windows appears.
Click Add…

3-10 Courier V.Everything Internal Modems: Getting Started

Select the port to which the Courier is connected.

When you click OK, Remote Access setup asks you if you would
like it to try to detect the modem connected to the port. Click
Cancel to select the Courier from a list.

Select US Robotics Courier V.34, and then click OK and exit
from Network setup. When you’re prompted to restart NT, click

Don’t Restart Now. Then, from Program Manager, click File |
Shutdown. When NT shuts down, power your computer off

and then on again.
Now RAS knows about the serial port and the Courier that is

attached. Next, you need to set up user accounts and access
privileges; those tasks are beyond the scope of this manual.

Communicating with the Courier 3-11

DOS

Because there is no communication capability built in to DOS,
you must install and run a third-party communications software
package to operate the Courier.

You must choose the COM port, IRQ, and the I/O address
within the communications application that you are using.
These are the standard I/O address and IRQ settings for each
COM port:

COM Port I/O Address IRQ

COM1 03F8 IRQ4
COM2 02F8 IRQ3
COM3 03E8 IRQ4
COM4 02E8 IRQ3

The Quick Link II diskette, which is included in the package
with the Courier, contains a DOS version of the software as well
as a Windows version.

For instructions about how to set up your DOS communications
software package, call our fax-on-demand service (at 800-762­6163 or 847-676-1598) or our BBS (at 847-982-5092). Request

Remember that you can use WinOS2 to run Windows
communications software packages.

To get the best performance, however, you should replace the
standard OS/2 serial port drivers COM.SYS and VCOM.SYS
with SIO.SYS and VSIO.SYS. You can get the enhanced drivers
from our BBS at 847-982-5092. Check file area 18, OS/2 Support,
Utilities, etc for SIO153.ZIP.

Linux

These are the standard I/O address and IRQ settings for each
COM port:

COM Port I/O Address IRQ

COM1 03F8 IRQ4
COM2 02F8 IRQ3
COM3 03E8 IRQ4
COM4 02E8 IRQ3

Nonstandard COM/IRQ settings are done by adding switches
(command line parameters) to the COM.SYS (or SIO.SYS) line in
CONFIG.SYS. For example, the following line selects COM3 and
IRQ5:

\OS2\BOOT\COM.SYS /i5/c3

For help with OS/2 Warp installations, download the file
WARPIN.ZIP from BBS file area 18, OS/2 Support, Utilities, etc.

For instructions about how to set up your OS/2 communications
software package, call our fax-on-demand service (at 800-762­6163 or 847-676-1598) or our BBS (at 847-982-5092). Request
document 10000 for a list of our technical support documents.

If you are using the Courier for dial-in only, set DIP switch 4 ON
and leave the other switches in their default positions. You may
need to set DIP switch 1 ON if your computer does not send a
Data Terminal Ready (DTR) signal.

If you are using the Courier for dial-in and dial-out, set DIP
switches 3, 4, 7, and 8 ON and leave the other switches in their
default positions. You may need to set DIP switch 1 ON if your
computer does not send a Data Terminal Ready (DTR) signal.

Communicating with the Courier 3-13

These are the standard port names and settings:

Outgoing Calls Incoming Calls Port IRQ I/O Address

/dev/cua0 /dev/ttyS0 COM1 4 03F8
/dev/cua1 /dev/ttyS1 COM2 3 02F8
/dev/cua2 /dev/ttyS2 COM3 4 03E8
/dev/cua3 /dev/ttyS3 COM4 3 02E8

Use the setserial command to tell Linux about any nonstandard
COM/IRQ combinations that you may have set using the
Couriers jumpers. Setserial also selects serial port speed and
I/O port address.

Linux has a built-in communications software package called
minicom. By default, minicom is located in the usr/bin
directory.

For instructions about how to set up your Linux
communications software package, call our fax-on-demand
service (at 800-762-6163 or 847-676-1598) or our BBS (at 847-982-
