Chapter 1
The Courier
The Courier V.Everything External Modem makes any computer or
terminal with an EIA/RS-232 serial port (or a Macintosh serial
port) 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 for 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).
The Courier 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.

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
The Courier 1-5
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 (800) 762-6163.
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.
1-6 Courier V.Everything External Modem: Getting Started
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.
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.
The Courier 1-7
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
The software for the external Courier has been developed to
support Plug and Play (as defined by the Plug and Play External
COM Device Specification, Version 1.00). When you connect the
Courier to a computer that uses a Plug and Play operating
system, such as Windows 95, the computer will automatically
detect and configure itself to the support the Courier.
Synchronous Support
The Courier can connect to synchronous serial ports to allow
access to mini- and mainframe computers. See Chapter 12,
Dedicated/Leased Line and Synchronous Applications, in the Courier
Modems Command Reference.
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.
1-8 Courier V.Everything External Modem: Getting Started
What You Need
A Computer or Terminal with a Serial Port
The Courier is compatible with any computer or terminal that
provides a serial port with an EIA-232 interface. See Appendix
A, The Serial Port, for details.
For top performance, your serial port must support speeds of
115.2 Kbps. For IBM-compatible PCs, make sure your computer
has a 16C550 UART. Check your computer’s documentation for
details.
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. The Courier is
shipped with a DOS/Windows communications software
package.
Installing the Courier 2-1
A Serial Cable
Because there are a variety of connector types that different
computers require, a serial cable is not provided with the
Courier. See the next section, Choosing a Serial Cable, for
guidelines.
Choosing a Serial Cable
Check the back of your computer for a serial port. Serial

Communicating with the Courier
After you’ve connected the Courier to a serial port and powered
the Courier on, you need to make sure that your computer can
send commands to the Courier. Once you’re sure that your
computer can communicate with the Courier, you’re ready to
start making or taking calls!
The methods of verifying communication with a modem vary
depending on the operating system your computer uses.
Windows 95 OS/2
Windows 3.x Mac OS
Windows NT RAS UNIX/AIX/Linux
DOS Mainframe OSs
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. Make sure
the Courier is powered on when you start Windows 95.
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.
Communicating with the Courier 3-1
Getting the INF File
Power on your computer with the modem installed. As
1
Windows 95 loads, it presents a New Hardware Found
panel. Select Standard Modem.
Start a communications software package (such as
2
HyperTerminal, which is included with Windows 95) and
dial the U.S. Robotics BBS at (847) 982-5092.
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
2
example, the TEMP directory.
C:\WINDOWS>cd\temp
Windows responds:
C:\TEMP>
Enter the following command:
3
C:\TEMP>
Windows responds:
1 file(s) copied
Be aware that the \inf directory is hidden, and even though it
may not appear, it is there.

Windows 3.x
Windows 3.x comes with a built-in communications software
package, Windows Terminal. You can use Windows Terminal to
test the Courier or you can install the communications software
package that is included in the package with the Courier.
Windows Terminal is in the Accessories group by default.
Because Terminal only supports speeds up to 19200 bps, you
will probably want to use a third-party communications
software package, such as Quick Link II instead. For Quick Link
II, see the section, Testing the Courier, on page 3-14. For other
Windows software packages, see Chapter 5, Setups for Common
Windows Software Packages.
For instructions about how to set up your Windows
communications software package, call our fax-on-demand
service (at 800-762-6163 or 847-676-1598) or our BBS (at 847-982-
5092). Request document 10000 for a list of our technical
support documents.
Communicating with the Courier 3-5
DOS
OS/2
Because there is no communications software built in to DOS,
you must install and run a third-party communications software
package in order to operate the Courier.
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.
You must choose the COM port to which the Courier is attached
in whatever communications software package you are using.
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
document 10000 for a list of our technical support documents.
To get the best performance, you should replace the standard
OS/2 serial port drivers COM.SYS and VCOM.SYS with SIO.SYS
and VSIO.SYS. You can get these enhanced drivers from our
BBS at 847-982-5092. Check file area 18, OS/2 Support, Utilities,
etc for SIO153.ZIP.
For help with OS/2 Warp installations, download the file
WARPIN.ZIP from BBS file area 18, OS/2 Support, Utilities, etc.

3-6 Courier V.Everything External Modem: Getting Started
Mac OS
Be sure you’re using a hardware handshaking cable to connect
the Courier to the Macintosh. Also, if you won’t be using
AppleTalk Remote Access (ARA), then set AppleTalk to Inactive
(in Chooser). Otherwise ARA may interfere with your
communcations software.
As a general rule, set DIP switches 1, 3, 5, and 8 ON, and use
AT&F1 as your modem initialization string.
For instructions about how to set up your Macintosh
communications software package, call our fax-on-demand
service (at 800-762-6163 or 847-676-1598) and request document
10000 for a list of available documents. Or, call our Macintosh
BBS (at 847-676-1598).
Windows NT
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.
Communicating with the Courier 3-7
Start Windows Terminal to verify that NT can communicate
with the Courier. Select the COM port to which the Courier is
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…
3-8 Courier V.Everything External Modem: 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 3-9
UNIX/Linux/AIX
If the Courier will be answering, set DIP switch 3 OFF; 4 and 8
ON.
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 UNIX, Linux, or AIX
communications software package, call our fax-on-demand
service (at 800-762-6163 or 847-676-1598) or our BBS (at 847-982-
5092). Request document 10000 for a list of our technical
support documents.

Other Features 4-1
The Voice/Data Switch
The Voice/Data switch allows you to alternate voice and data
over the same connection. You call the remote user by
telephone, then you each press the Voice/Data switch on the
Courier. After you’re finished sending and receiving files, press
the Voice/Data switch to return to voice.
You can accomplish the same function by sending AT
commands, and you can also assign a different function to the
Voice/Data switch if you don’t plan to use it for alternating
voice and data.
Changing back to voice after the modems connect requires that
both modems have handset exclusion. Handset exclusion means
that when the modem is using the phone line, the modem
automatically disconnects the phone (handset). If you keep the
handset off hook, once you hang up the modem, the handset
takes over the phone line and you can use voice communications
again.
If the remote user does not have handset exclusion, you may not
be able to switch back to voice mode successfully once you have
switched to Data mode.
If the remote user does not have a Voice/Data switch, he or she
can follow the instructions for using the appropriate AT
command. See the next section for details.
Using the Voice/Data SwitchS32=1, S32=2
Either user can start the call, but you need to decide up front
which modem will originate and which will answer.
Send the modem that will originate ATS32=1 <Enter>
1
Sending ATS32=1 tells the Courier to go on line and send
ATD <Enter> when you press the Voice/Data switch.
Send the modem that will answer ATS32=2 <Enter>
2
4-2 Courier V.Everything External Modem: Getting Started
Sending ATS32=2 tells the Courier to go on line and send
ATA <Enter> when you press the Voice/Data switch.
NOTE: If you’ve stored a command string (using
&ZC=s), the Courier will default to S32=9, which
executes the stored command string when you push the
Voice/Data switch.
Call the remote user (make a voice call) or have them call
3
you. You must the phone that is attached to the Courier’s
PHONE port.
When you’re ready for the modems to connect, press the
4
Voice/Data switch of the “originating” modem (the one that
set S32=1). The handset goes dead. Do not hang up the
phone.
Immediately afterward, press the Voice/Data switch of the
“answering” modem (the one that set S32=2). The modems
go through the normal negotiation process.
If the answering modem has handset exclusion, the
answering user should not hang up the phone either.
If the remote modem doesn't have handset exclusion, you
can try to switch back to voice later. Or, you both can hang
up your phones as soon as the modems go off hook.
Using CommandsATD, ATA
If your Voice/Data switch is set for a function other than
Voice/Data operations and you don't wish to change it, use AT
commands.
Make a voice call to the remote user (or have the remote user
1
call you). You must both use telephones that are connected
to the PHONE port of your modems.
Other Features 4-3
If you are to originate the connection, type the following
2
command:
ATD <Enter>
NOTE: Be sure the modem is not set to X2, X4, X6 or X7,
or it will return the NO DIAL TONE result code and
hang up.
The remote user should type the answer command:
3
ATA <Enter>
If the remote modem also has handset exclusion, leave both
4
phones off hook in case you wish to switch back again to
voice after your data transfer. If the remote modem doesn't
have handset exclusion, switching back to voice may not be
successful. If you don't want to switch back to voice later,
hang up both phones as soon as the modems go off hook.
Changing the Function of the Voice/Data Switch
Use Register S32 to set the voice/data switch for the function
you desire. The default is S32=1pressing the switch forces the
modem off hook in Originate mode.
Holding the switch in when you power on the modem causes it
to perform a power-on self-test.
NOTE: Some of the applications listed below require preconfiguration. Review the Chapter (from Table 4-1) in the
Courier Modems Command Reference before assigning the
Voice/Data switch function.

You can program the voice/data switch to execute a stored
command string when pressed. The following example assigns a
command string that displays the link diagnostics screen when
you press the voice/data switch.
AT&ZC=I6 <Enter>
Set the voice/data switch function to execute stored command
string by setting Register S32 to 9 with the following command:
ATS32=9 <Enter>
Note that you can reset the voice/data switch at any time to one
of the other available functions. Additionally, you can overwrite
the stored command string with a new one at any time.
Once you've stored your command string and set Register S32,
press the Voice/Data switch whenever you want the Courier to
send the command string.
Other Features 4-5
Getting Information About Calls
Here are the commands that provide detailed information about
your current settings and current and last calls.
To get call-in-progress data and current settings while you are
on line, set DIP switch 9 OFF and then send ATZ <Enter> (or
power the Courier off and then on).
Alternatively, you can send ATS14.0=0 <Enter>, but be aware
that the DIP switch setting will override your setting at power
on or reset (even if you add &W to write the command to
NVRAM).
Once you’ve set DIP switch 9 or sent ATS14.0=0 <Enter>, you
can type the following command to get to online command
mode, and the Courier will not hang up:

MI/MIC Operations
Couriers are shipped with MI/MIC disabled, that is, for normal
use. Mode Indicate/Mode Indicate Common (MI/MIC) closure
is required for some applications where existing hardware, such
as a PBX, does the dialing.
For these applications, the Courier must power up in Originate
mode. Then the Courier goes on line and accepts data when it
connects with the number dialed by the system equipment.
Once you've set Register S34, have the system force the modem
off hook by closing the MI/MIC leads in the phone line
connector.

status light goes on. If you dialed a number, listen for an
answer tone from the remote modem.
Then drop the DTR signal. The modem should go on hook
and the OH status light should go off.

reassemble the Courier.
Troubleshooting
If the Courier does not respond to MI/MIC closure, or if the
Courier fails to go back on hook when the computer or terminal
drops the Data Terminal Ready (DTR) signal, your phone
equipment probably reverses MI/MIC polarity.
You can solve this problem by reversing the modem's MI/MIC
wiring. Do this by resetting the two jumpers on the printed
circuit board.
Follow the steps from the previous section. This time, set the
jumpers as follows:

This digital apparatus does not exceed the Class B limits for
radio noise emissions from digital apparatus set out in the radio
interference regulations of Industry Canada (formerly Canadian
Department of Communications).
Le présent appareil numérique n'émet pas de bruits
radio-électriques dépassant les limites applicables aux appareils

The Industry Canada (formerly DOC) label identifies certified
equipment. This certification means that the equipment meets
certain telecommunications network protective, operational, and
safety requirements. The department does not guarantee the
equipment will operate to a user's satisfaction.
Before installing this equipment, make sure you are permitted to
connect it to the facilities of the local telecommunications
company. You must also install the equipment using an
acceptable method of connection. In some cases, you may also
extend the company's inside wiring for single line individual
service by means of a certified connector assembly (telephone
extension cord). You should be aware, however, that
compliance with the above conditions may not prevent
degradation of service in some situations.
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by a user to this equipment, or
equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
