How to add serial port?
How old is your motherboard? FC2 is 5 or so years out of date, so it may well not recognise your hardware. Since Fedora 11 was released a couple of days ago, why don't you try something a bit more modern?
By default only 4 serial ports are configured in the linux kernel. Look for the "setserial" or a similarly named package for your distribution that is used to configure systems with more than 4 serial ports.
Here's a link to another thread about additional serial ports. In one of the posts is yet another link, leading to yet another post. You may find some useful information at these locations.
