U.S. ROBOTICS: THE INTELLIGENT CHOICE IN INFORMATION ACCESS C ongratulations! You have just purchased the Sportster® Voice 56K faxmodem. Since 1976, U.S. Robotics has grown to become a key manufacturer and developer of information access technology. U.S. Robotics’ advanced technology allows you to use your faxmodem to open up a new world of information access.
WELCOME TO X2 INFORMATION ACCESS However, due to FCC rules which restrict power output of your service provider’s modems, current download speeds are limited to 53Kbps. This modem is easily upgradable to new features and enhancements as they become available. An integrated end-to-end solution from the leader The latest breakthrough in online communications Until now, 33.6 Kbps was thought to be the practical limit for speed over standard phone lines.
W ELCOME TO X2 INFORMATION ACCESS Taking advantage of the modern telephone network x2 technology uses the increasingly digital telephone network to bring you faster downloads, by eliminating the analog-to-digital conversion in the downstream path. x2 takes advantage of the typical network configuration found when an analog subscriber connects to a digitally connected server.
PRODUCT FEATURES Your new x2 modem provides many advanced features. Here are just a few: Modulation Schemes x2 technology ITU-T V.34+ ITU-T V.34 ITU-T V.32bis ITU-T V.32 ITU-T V.22bis ITU-T V.22 ITU-T V.23 Bell 212A ITU-T V.21 Bell 103 Error Control and Data Compression Schemes ITU-T V.42 ITU-T V.42bis 4 MNP 2-5 Fax Modulation Schemes ITU-T V.17 ITU-T V.29 ITU-T V.27ter ITU-T V.21 Fax Standards EIA 578 Class 1 FAX EIA 592 Class 2.0 FAX V.
PRODUCT FEATURES Speakerphone With the addition of an inexpensive set of externally powered speakers, your new Sportster Voice modem provides all the convenience of a full-duplex speakerphone. Unlike many half-duplex speakerphones, your Sportster allows you to converse normally without annoying echoes and distortion. Simply plug the speakers into the SPEAKER jack on the modem and you’re ready to go.
PART I - INTERNAL MODEM INSTALLATION READ THIS FIRST! Part I, Section A: Internal Modem Installation with Windows 3.x (page 7). If you have an internal modem and are using the Windows 95 operating system, start at Part I, Section B: Internal Modem Installation with Windows 95 (page 40). This part of the manual covers the installation of your internal Sportster and the accompanying fax/data/voice software. The instructions are provided for both Windows 3.1/ 3.11 (hereafter jointly referred to as Windows 3.
SECTION A: INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X You’ll need these items from your Sportster box: modem phone cord Connections CD THIS FIRST SECTION WILL WALK YOU THROUGH THE STEPS INVOLVED IN CONNECTING YOUR SPORTSTER TO YOUR COMPUTER.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X A Word about COM Ports and IRQs Most computer accessories — a mouse, sound card, enhanced graphics card, scanner, etc. — require a special connection through which they can communicate with the computer. For an internal modem, it’scalled a communications (COM) port. Most computers have 1 or 2 COM ports but can have up to 4. On an internal modem, the COM port is represented by the modem itself.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X D KEY POINT: Accessories cannot share COM ports and should not share IRQs. When accessories try to share settings, they will either not work properly or not work at all. This section of the manual will help you understand the COM/IRQ settings on your new Sportster. U.S. Robotics has set your Sportster to use COM 2 and IRQ 3. This is the industry standard for modem settings. In most cases, these settings will work.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X the program that determines which COM ports and IRQs are available for use by your modem. 3. The screen at the top of the next page appears when ComTest starts. • If there is a modem in your computer which you are replacing with your new Sportster, you need to go to “Testing an Installed Modem” on page 13 to determine which options to select so that ComTest can detect what the older modem’s COM and IRQ settings are.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X 5. If you have a free setting, you will see a screen like this. COM2/IRQ3 is free in this example. ComTest might instead recommend COM1/IRQ4, COM3/IRQ4, or COM4/IRQ3 for your modem. Click on the Next button. If you DO NOT have a free setting, you will see a screen like this. Click on the Finish button to exit ComTest. Go to “What to Do with ComTest’s Recommendation” on page 14.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X 6. When you see this screen, click on the Finish button to exit ComTest. Go to “What to Do with ComTest’s Recommendation” on page 14. Testing an Installed Modem If there is a modem already installed in your computer, you can determine its COM and IRQ settings by selecting the Test an installed modem option. Follow the instructions on 12 screen until you see the screen that tells you “Testing is complete.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X What to Do with ComTest’s Recommendation NOTE: If your communications software requires a setting for your modem that ComTest does not recommend, there is a good chance that the setting is being used by another device in your system. To find out how to free that setting in your system, consult your computer manufacturer’s manual. If the communications software requires COM2/IRQ3, go to “How to Insert the Modem” on page 19.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X If ComTest recommended COM3/IRQ4 or COM4/IRQ3 Do not use either of these settings. While the COM port part of the setting is acceptable (ComTest only recommends COM ports that are not being used), the IRQ part of the setting is not acceptable. When ComTest recommends either COM3/IRQ4 or COM4/IRQ3, the IRQ in the setting is being used by another accessory.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X • Then return to this point in this manual to continue. After disabling COM2, you can use the COM2/IRQ3 setting. Write “COM2” and “IRQ3” on the first page of this manual and go to “How to Insert the Modem” on page 19. If ComTest tells you that You do not have any available COM ports and/or IRQs We recommend you disable COM1 or COM2. When you disable one of these COM ports, you can use it and its default IRQ for your modem.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X down on the first page of this manual. Go to “How to Insert the Modem” on page 19. How to Change the Factory Settings (NOTE: If ComTest recommended COM2/IRQ3 for your modem, you can skip this section.) 1. Always touch an unpainted metal part of your computer (the back is usually unpainted) to discharge static electricity before handling the modem. Static can damage your modem. 2. Take the modem out of its plastic bag. 3.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X TIP: Grasp the shunts with a tweezers or needle-nosed pliers. DO NOT grasp too firmly, as you may crush the shunts. If a shunt seems stuck, gently rock it back and forth as you lift. Do not touch any other part of the modem or your computer with the tweezers/pliers. 5. Move the shunt to the new setting. • The COM port setting can involve one to three shunts.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X 1. Turn off your computer and unplug it from the electrical outlet. 2. Unplug any peripheral devices (printer, monitor, keyboard, mouse, etc.) from the computer. TIP: Before you unplug anything, label the cords or make a sketch of how things are connected. This can be helpful when you plug things back in later. CAUTION : To avoid risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged.
PART I: SECTION A: INTERNAL M ODEM INSTALLATION WITH W INDOWS 3.X 4. Find an empty ISA expansion slot that’s at least as long as the gold edge of your modem.

PART III: SECTION C: GLOSSARY ASCII auto dial American Standard Code for Information Interchange. A code used to represent letters, numbers, and special characters such as $, !, and /. A process where your modem dials a call for you. The dialing process is initiated by sending an ATDT (dial tone) or ATDP (dial pulse) command followed by the telephone number to dial. Auto dial is used to dial voice numbers. See command Dn.
PART III: SECTION C: GLOSSARY bit rate byte Also referred to as transmission rate. The number of binary digits, or bits, transmitted per second (bps). Communications channels using telephone channel modems are established at set bit rates, commonly 2400, 4800, 9600, 14,400, 28,800 and higher. A group of binary digits stored and operated upon as a unit. In user documentation, the term usually refers to 8-bit units or characters.
PART III: SECTION C: GLOSSARY characters per second (CPS) cyclic redundancy checking (CRC) A data transfer rate generally estimated from the bit rate and the character length. For example, at 2400 bps, 8-bit characters with start/stop bits (for a total of ten bits per character) will be transmitted at a rate of approximately 240 characters per second (cps). Some protocols, such as error-control protocols, employ advanced techniques such as longer transmission frames and data compression to increase cps.
PART III: SECTION C: GLOSSARY data compression table default A table containing values assigned for each character during a call under MNP5 data compression. Default values in the table are continually altered and built during each call: The longer the table, the more efficient throughput gained. Any setting assumed, at startup or reset, by the computer's software and attached devices. The computer or software will use these settings until changed by the user or other software.
PART III: SECTION C: GLOSSARY digital loopback duplex A test that checks the modem's RS-232 interface and the cable that connects the terminal or computer and the modem. The modem receives data (in the form of digital signals) from the computer or terminal, and immediately returns the data to the screen for verification. Indicates a communications channel capable of carrying signals in both directions. See half duplex, full duplex. digital signals error control Discrete, uniform signals.

See commands &Hn, &In, &Rn.
PART III: SECTION C: GLOSSARY ITU-T local echo An international organization that defines standards for telegraphic and telephone equipment. For example, the Bell 212A standard for 1200-bps communication in North America is observed internationally as ITU-T V.22. For 2400-bps communication, most U.S. manufacturers observe V.22 bis. The initials ITU-T represent the French name. In English it is known as the International Telegraph and Telephone Consultative Committee.
PART III: SECTION C: GLOSSARY nonvolatile memory (NVRAM) originate mode User-programmable random access memory whose data is retained when power is turned off. On the Sportster, it includes four stored phone numbers and the modem settings. The mode used by your modem when initiating an outgoing call to a destination modem. The transmit/receive frequencies are the reverse of the called modem, which is in answer mode.
PART III: SECTION C: GLOSSARY protocol remote echo A system of rules and procedures governing communications between two or more devices. Protocols vary, but communicating devices must follow the same protocol in order to exchange data. The format of the data, readiness to receive or send, error detection and error correction are some of the operations that may be defined in protocols. A copy of the data received by the remote system, returned to the sending system, and displayed on the screen.
