Rockwell modem device driver version 2.1.2.161.003 README

This update package installs the Microsoft(R) Windows(R) 98 device driver for the Rockwell modem that comes preinstalled in your IBM(R) Aptiva(R) computer. This is a V.90 device driver, which enables faster connection speeds over normal phone lines than the 33.6 kilobits-per-second (Kbps) speed that can be achieved with the industry-standard V.34 device drivers.

This update package is intended for IBM Aptiva machine types 2158-xx, 2163-xx, 2164-xx, 2170-xx, 2171-xx, 2172-xx, and 2174-xx. Your Aptiva computer, depending on the model, might have come with a device driver for the 56K modem; this is an upgrade to that device driver.

LIMITATIONS
___________

Although this device driver enables your modem for 56-Kbps
connections, you might frequently obtain connections slower than
56 Kbps, for any of the following reasons:

o The maximum connection speed that is possible is approximately
53 Kbps, because of United States Federal Communications
Commission (FCC) limits on telephone-company power.

o The service to which you are connected must support the V.90 or
K56flex standard to obtain a high-speed connection. Most of
the common online services, such as AOL and CompuServe, support
V.90, K56flex, or both.

o Excessive electronic interference (noise) on your phone line
can reduce your connection speed.

o If your telephone company uses more than one analog-to-digital
conversion, your connection speed will not exceed 33.6 Kbps.

o The V.90 and K56flex standards are available only through
service providers with a direct digital link to the telephone
company. For example, if you connect your modem to the modem on
another computer to play a game, 33.6 Kbps is the maximum
connection speed you can obtain.

o The high-speed digital data connections enabled by V.90 and
K56flex are only for data that your modem is receiving. Data
that is transmitted from your modem is limited to a speed of
33.6 Kbps.
