    I've used a max232 on what I thought was a cheap 5 volt usb adapter, and it did work. Now I have to check on an oscilloscope to make sure it was as cheap as I thought.

    Since you are just at ttl levels you could do this trick with the 18F4550 without a max232, but you are SOL without a max232 on the 16F devices.
