Not true. Just as long as whatever application you're using frees up the resource after its done, then its fine. The two apps can't be trying to use the port at the same time. If you're using NT, its a Protected OS, everything has to go through the Kernel. You can't directly talk to hardware.

Would it be tricky to install one of those serial cards with two ports? I'd also like to install a card with a couple of extra parallel ports for a scanner so it wouldn't be going through my printer. I know the very basics (can recognize the motherboard and the slots etc when I take off the cover, have installed memory chips, messed with jumper switches)--I think I might be able to do it. Have started wondering if it wouldn't be more cost effective to just buy a new pc, but not able to do that just now.
No, provided that you know a bit about IRQs, and DMA's. Its not bad at all if you know what resources you have available to you. The trick is to make sure you buy a card that allows for non stand IRQ's and DMA's too. That way, if the standard ones are taken by the MB, then you can just assign non standard ones to it.
