Yeah, I would just say it's easier to build or buy a serial interface. I mean this is about having fun, testing, and learning. A MAX232/233 is cheap or even an MC1489 (4 for $1.00). I used an old Dave card loader or some such nonsense that had the MAX232, caps, pwr supply, and serial port already on it.
