Modem on COM3 in WinXp

I have an old P2 PC running WinxP professional but the modem is not
functioning but believed to be in good condition.

The modem did work originally, but I had to go into the control panel
and select phones/modems and diagonistics and "query modem" to get it
to work. It would not work on bootup.

Recently, it doesn't work at all and is listed as "not present"
in the phones/modems section of the control panel.

I attempted to install another generic 56K modem on Com2
but that also doesn't work.

The modem is not detected by the p-p install wizard and it has
a jumper installed on one of 5 possible locations.

I suspect it is a non-plug and play modem and is set for com3 or 4 but
I cannot install Com3 or 4 using the "add hardware" wizard. The wizard
says to click on "Add a new hardware device" but there is no button to
click on.

Any ideas how I can add Com3 or 4 to a WinXp system and test the modem
on those addresses?

Thanks,

Since running XP, Modem has worked? Did you change anyhing?
What is make and model of Modem?
Do you have Win XP drivers?
Sounds like modem isn't PNP.
What is jumper settings? IRQ? COM?
Do yuo have a manual?
Write down jumper settings. Then remove all jumpers. Install and Boot up.
Where did other modem come from? Make? Model? Is it PNP?
Install should auto assign Com port.

Modems are pretty cheap!! Most new are auto recognized by Win XP.
 
New modems are cheap enough these days.. treat yourself to a new one that
you know will work.. ensure that you take any older installations out of the
configuration.. XP will set it up as COM3 by default..

I'm pretty sure the internal modem is not p-p and is jumpered for com3
and whatever IRQ is needed. There are no markings on the jumpers and I
don't have a manual. The modem was working, but only after "quering" it
from the control panel.

I did make some changes in the bios because both com ports were set to
Com1, so I changed one of them to Com2.

But, I am unable to add Com3 using the add hardware wizard. Adding a
new port comes out as Com4. And adding another port comes out as Com5.
Then the device manager lists the ports as Com1, Com2, Com4 and Com5.

How do I get the thing to install Com3?

No need for a new modem, this old junker works fine. I took it out and
studied the jumper settings, and discovered the IRQ was set to 3 and
not 7 as indicated by windows device manager. Changing the IRQ setting
in windows fixed the problem. I'm using the old modem now to post this
message.

Thanks,

I assume that it is an old ISA modem.. PCI modems work better generally
although with varying quality of telephone lines, you may not see any real
difference..
