UART switch not working [EDIT: I got it working]

Make sure your terminal is set for 1.500.000 baud.  I know the first time I did it, I misread it as 150.000 baud.

I made a cable from old headphones and a Tigard tool switched to 3.3V, and I double checked the values with a meter. I think I had 1.5M baud set correctly, but I'll try again tomorrow.

Thanks for the clarification about the sound behavior, that wasn't obvious from what I had read!
