Sportster Vi 14.4k/28.8k/33.6k modems bought BEFORE January 1996
Windows 95/98/NT 4.0 driver
From Device Manager, remove all Com ports provided by the modem installation (for example, if it is an internal modem creating a Com port, remove it). Copy the attached .inf files to your c:\Windows\INF directory. This should be done using the command prompt on most systems since the .\INF directory is typically marked as hidden. Delete all .bin files from the c:\Windows\INF directory. Restart the computer. If the modem is in "PnP" mode, it should be auto-detected and installed. If the modem is in legacy mode, the user will need to install the modem manually.
