Certain full-featured sound cards require three IRQs to support all their
functions. When one becomes available, they take it. This situation re-
quires that you remove your sound card, free an interrupt, install the
modem and verify its operation, and then reinstall the sound card. This
procedure may also work for sound cards that have lost their sound after
the modem has been installed or if the modem will not install in a system
with a sound card.
Uninstalling the Modem: If you are uninstalling the modem in Windows
95 in order to upgrade your drivers or to obtain a “clean” reinstallation,
it is important to follow these directions carefully. Because this modem
uses virtual device drivers, following these instructions out of sequence
will result in “freezing” your system. (note: For Windows NT, use the
installation utility on the Windows NT installation diskette. The utility
has an option to remove your modem drivers.)
1) Within Windows 95, go to Start-Settings-Control Panel and double-
click the System icon. Select the Device Manager tab. From the device
tree, double-click the Modems icon to expand the modems tree. High-
light your modem by clicking once on the icon next to your modem and
then click the Remove button.
2) Go to Start-Settings-Control Panel and double-click the Modems
icon. If your modem is listed, highlight the modem by clicking once on
the icon next to the modem and then click the Remove button. Or, if the
New Hardware panel comes up, click on the Cancel button. (Note: Your
modem should not be listed in the Modems section after you have de-
leted it from the Device Manager. This could be a sign that your Plug-
N-Play settings are not correct. See the Does Not Install section for info
about Plug-N-Play).
3) Close all open window panels and return to the Windows 95 desktop
screen. Go to Start-Find-Files or Folders and search for the following
files which the modem uses. Type in the name and extension (i.e..
ltwave.inf) and click on the Find button. Once you find each of the files
listed, highlight the file by clicking once on the file name and then go to
File-Delete. Delete all occurrences of these files. (Do not delete these
files from your modem installation diskette. You will need your diskette
to reinstall the modem).
