I have a DEll 4600 running XP.  I'm using an external modem for DSL.

When I want to get photos from my digital camera onto the computer, it get's hooked up to the serial port.  The serial port is also used to program my X10 module.  Niether is done at the same time.

On my last computer, both worked on COM2.  On this machine when I try to use them, I get no connection and they indicate COM2 is in use by another program or piece of hardware.  I know the internal modem for voice and fax is using COM3.

How can I find what is using COM2.  I get no connection when trying to get the camera or X10 module on COM1.

Last....both of these devices worked when I first installed them and their software on the computer.
