serial cable

Hey, I ordered the serial cable coming from dealextreme and it has not arrived yet. I noticed today that the link was taken off the wiki due to it not being at TTL levels. I was wondering if I bought a Nokia serial cable (the ones that have the prolific chips in them) which runs at 3.3v out of the box, could I just connect the tx and rx pins to the cable I had bought and it would possibly work or would that be a bad idea and I should cut my losses and kill the order. -- -Tom
