After installation is complete, a 3Com Modem Setting application is installed in
the Control Panel. Open Modem Setting to change the COM port assignment for
the LAN+Modem card. Dell’s default is COM5. You may need to change the COM
port to a lower number if you are using older software that does not recognize
COM ports higher than 4.
With the default audio settings for Windows 98, you may not hear the sound
from the modem when you dial out. To enable the sound, use the following
procedure:
1 Locate the speaker icon in the system tray.
If there is no speaker icon in the system tray, open the Control Panel and
double-click Multimedia. On the Audio page, make sure Show volume control on
the task bar is checked
2 Double click the speaker icon in the system tray.
3 When the Master Out window opens, select Options.
4 Choose Properties and make sure the Mono In box is checked. Click OK.

the mute box is unchecked.
