Comm port problem in XP when using X10

My XP box does have IRQ 3 assigned to Comm port 2.

To attempt to change resource assignments in XP, open System Properties.

(right click on My Computer or open Control Panel)

Click on the Hardware tab.

Click on Device Manager.

Expand the Ports branch.

Right click on Comm 2.

Click on the Resources Tab.

Un-check the configuration check box.

Create / select a hardware profile and assign IRQ 3 to the Comm port.

Another thing to check, is that the settings for the COMM ports in the motherboard BIOS setup are correct.

In Microsoft Word, when you go to "help: then "about", then "system info", IRQ 3 is blank. But when i try to assign comm port 2 to irq 3, it says it's in use. )Commport 2 is currently assigned to IRQ 11.) I searched through the rest of the hardware and can't find where IRQ 3 is in use. Still looking for options.solutions. Thanks.
