how about trying Hiren´s boot cd ? It has a minimal windows xp in it, then
you can load putty from a usb drive
Also, the serial ports are still enabled in bios, right ?

Okay, I'm not having any luck with this at all.
I tried a Ubuntu Live CD 13.10 but that doesn't have Putty or Minicom
installed by default, and trying to install it from a terminal using "sudo
apt-get install putty" results in an error saying E:\ unable to locate
package putty. I'm guessing because the Ubuntu Live CD 13.10 is trying to
install the package from the E:\ (cd) drive instead of the internet. (I
also tried sudo apt-get update, but that didn't help either)
So, I tried a Fedora 19 Live CD. I was able to install putty on it using
"sudo yum install putty" and I now have putty available, but whenever I
start up putty and select Serial, it automatically tries to use the
/dev/ttyS0 port at 9600, but errors with a "Unable to open connection to:
unable to open serial port" ... I'm guessing because the serial port isn't
actually active or turned-on in the OS yet since it's merely a Live CD? I
also notice that when in the /dev directory there is no ttyS0 or ttyS1 in
it... So..
I'm stuck. Any know how to enable the serial port in the Fedora 19 Live CD?
My linux knowledge is about NIL.

Careful using cu (if it even exists on modern linux distros).
It's generally still packaged by "full" distributions, but live CDs
have to be more choosey about what they provide "out of the box", and
I expect the "uucp" label looks unappealing. :)
IIRC, cu doesn't do any handling of the modem and flow control lines, so
you
are at the mercy of whatever the defaults are for whichever serial port
device
file you are using.
That's what stty(1) is for. :) E.g., this sets 9600 baud, 8 data
bits, no parity, 1 stop bit, RTS/CTS off, XON/OFF off (and yes I had
to look the options up):
stty /dev/ttyS0 9600 cs8 -parenb -cstopb -crtscts -cdtrdsr -ixon
