Are you sure the cable wired correctly? If im not mistaken, a PS2 mouse cable looks pretty much the same, but has two of the leads crossed or something. You might want to check the cable against the pin-out on alesis' site.
Your serial port may well be to old too. (a serial port card is cheap though).
