Go to Start>Settings>Control Panel,double-click the System icon,click the Device Manager Tab,go down the list to PORTS and it will have the enabled Com Ports here,click the Plus and in the sub-tree highlight the com port and click on properties.
You can review each device in this manner,highlight the device and click the properties button and it will show the com port being used.

From Norton System Works 2000, Norton Utilities, try Norton Diagnostics. That one will show what's being used on all of your available com ports and even let you test them for errors.

Have Fun!!!

Windows 98 does not have a dialog windows that displays which port is connected to which device. You must goto into control Panel and click on the devices you know that are connected to your comm ports. If you wanted to know what IRQs are being used for your comm ports you can find that out in device manager by double clicking the first item listed in device manager labeled "COMPUTER". You already uninstall your modem, and you uninstall your infared devices. What other devices do you have install on your comm port. If you have no devices attach to any of your comm port it could be possible that you have used up all your IRQ's. Are you getting any Device status icon displayed next to any of your devices listed in device Manager? Check your startup folder to make sure you don't have a device taking up a port such as a palm pilot.
If you do then you will need to close out that program from your startup or remove from your startup to free up a port. Provide a little more info on the devices you have attach to your pc. Thanks

I'm going to assume that your com2 port is hardwired on your motherboard. By default this port will use IRQ 3. If you go to Start/Programs/Accessories/System Tools/System Information. Expand Hardware Resources and click on IRQs you will get a list of your used IRQs and a description of the device that is using that particular IRQ.

As above, I'd bet that the com port is hardwired into your system board. You should be able to disable it in your BIOS setup. That's the first thing I do with a new system since I never used the attached serial ports. All system boards are a little different, but typically they are under advanced/integrated peripherals.
