Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I installed fedora core 2 and run command "dmesg | grep ttyS"
Quote:
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x2f8 (irq = 4) is a 16550A
ttyS2 at I/O 0x3e8 (irq = 11) is a 16550A
ttyS3 at I/O 0x2e8 (irq = 10) is a 16550A

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 FC2 is 5 or so years out of date, so it may well not recognise your hardware.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.
