I have a Pioneex system with 2 com ports. I can't get anything to work on com 2.  My system has a modem card installed which uses the com 2 settings.  What do I need to do to be able to use the second com port.

Your motherboard may have its own COM1 and COM2 ports.
So, enter BIOS-setup mode, and "disable" that COM2 port.
Then, your internal modem can "claim" control of 'COM2'.

HI Otta,
         What I want is to reclaim com port 2 to use it for a digital camera.  Can I assign the modem to another setting.

Try this:
Remove the modem from device manager then shut down and "remove" the modem, reboot and make sure there is no listing for the modem, if there is remove them, if not then shut down and install the camera, boot up and install any software you need for the camera to work, make sure there is no conflicts in device manager, now shut down and reinstall the modem, boot up and let Win find the modem and install it, it should install it somewhere else (com 1) now since you have the camera installed to com 2

That's the same problem that I had.

> Can I assign the modem to another setting?

Yes.  I enabled the motherboard's COM2 port,
and connected my camera to that port,
and I set the jumpers on my modem to COM4/IRQ3, and it works fine.
The only restriction is that I cannot use both devices
at the same(!) time, since both COM ports use IRQ3,
and neither device likes to "share" that IRQ.

Does your modem have jumpers (to set the COM and IRQ values)
or is it strictly Plug-and-Play?
What's the specific manufacturer & model-number of your modem?
