cannot install modem

I have a second pentium PC running winnt with sp3.
I'm trying to install a US Robotics modem but have
no documentation; it looks like a newer model
(includes PNP), with these numbers:
FCC ID: CJE-0335
My cmos setup shows two com ports: com1 and com2,
the IRQ for the modem is set there at: IRQ 3
The card is set to PNP (no jumpers).
I've tried to install it with diferent US Rbotics
models, even added more com ports ( on Control
Panel > 'ports' )with no luck.
Can anyone shed some light here?, what's the proper
way to install it from scratch?.
TIA for any help or suggestion.

WinNT is not Plug & Play, so you will have to manually configure the jumpers on the modem to match whatever free com port/irq you have available.

Com1 & Com3 generally use irq4, Com2 & Com4 generally use irq3.

If you have no devices using Com1, start by setting the modem jumpers to Com1 and irq4.

If you can't figure out which jumper is which, go to:

they have an online manual that should point you in the right direction.

Use the FCC ID # and look up your modem at
http://www.fcc.gov/fcc-bin/ead
you may have more information available at this location.
At the very least, it will give you the EXACT model number so you can search the NET
for specific answers.

If you are so inclined, on your NT4.0 WS cd rom there is a directory called pnpisa.  If you go in there and install the .inf file, it will enable pnp for you.  You may or may not wish to do this - at any rate, make sure the make and model of your modem is on the latest Hardware Compatibility list at Microsoft.  you will find this will alleviate a lot of your installation problems for hardware under NT 4.0
