If you are installing the PCI card in Windows 95/98, run setup on disk two of the

Selecting the PCI COM Number in Windows 95
When installing a PCI Serial Adapter in Windows 95 or 98, the default COM
numbers assigned to the two ports will be COM5 and COM6 if those numbers are
not already assigned. If they are assigned to other devices, the next available COM
numbers will be assigned to the ports.
To change the two ports so that Windows assigns them to COM3 and COM4:
1. Double-click the “Systems” icon in the control panel or right-click on
“My Computer” and choose “Properties,” which will bring you to
“System Properties.”
2. Choose the “Device Manager” tab and double-click on the “Multi-Function
Adapter” heading. This will show all the information concerning the PCI
Serial Adapter.
3. Choose the “Resources” tab, which will show all resources assigned to the PCI
Adapter. Uncheck the “Use Automatic Settings” box. Three input/output
(I/O) ranges will be listed. The first I/O range is for the PCI bus and should
not be changed. The second and third I/O ranges are the ones that need to
be changed in order to have those ports set to COM3 and COM4.
4. Double-click on the second I/O range, which will allow you to change the
address. Highlight the entire I/O range and type 03e8–03ef for COM3. Click
OK. Windows will inform you that you have made modifications that may
affect other devices. Click OK.
