PS/2 is not an rs-232 based communication. If you have a USB port, you may
have a slim chance of getting it to work. Best bet is to go buy a notebook
with "real" ports on it.

Yes, Rufus, believe it or not, many laptop manufacturers feel that we no longer need a serial port. I guess they think that a USB port is all that's needed? I hope that keyboards remain for a while! ;oP
As for Juan's dilemma... I have had good results using a PCMCIA serial card to add a second COM port to my Toshiba. The one I use is made by Socket Communication:
Your best bet is a USB to serial convertor, but that does require that your notebook has a USB port, your software can access serial ports with
higher-than-usual-numbers.
Absolutely it is possible to buy a laptop without a serial port - the cheaper Compaqs don't have one! We had to buy a PCMCIA serial port adapter to use our PLC software when someone bought us a laptop without checking the specs well enough.
