WELCOME TO X2 INFORMATION ACCESS power output of your service provider’s modems, current download speeds are limited to 53 kbps. This modem is software upgradable, allowing easy upgrades 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.
WELCOME TO X2 INFORMATION ACCESS Taking advantage of the modern telephone network compression, x2 can download at speeds up to a blistering 115.2 kbps. x2 technology takes advantage of the typical network configuration found when an analog subscriber connects to a digitally connected server. Because it requires no analog-to-digital conversions in the downstream path (which can cause line noise), x2 can use nearly all of the available 64K network bandwidth.

BEFORE YOU BEGIN (WINDOWS 95 USERS) Your Sportster modem is a Plug and Play device. Windows 95 can automatically identify a Plug and Play device and determine if your system has the resources necessary to support the device. However, Plug and Play will not work if you do not have resources available or if devices on your system are not reporting resource usage correctly. Here’s how you can verify that your system has the necessary resources before installing the modem. 1.
INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X You’ll need these items from your Sportster modem box: modem Connections CD Plus: a screwdriver (not included) phone cord 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 some devices, this connection is called a communications (or COM) port.
INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X a task. The computer stops what it’s doing, depending on the priority of the request, to help the accessory perform its task. When two accessories share an IRQ, it’s like two people asking different questions in unison to a third person. Just as the person being asked the two questions cannot understand either request, a computer can lock up or otherwise fail to communicate properly with your modem when there is an IRQ conflict. U.S.
