Hi Brian, I don't understand. Are you saying that I need to add still more parts to get an RS-232 to TTL adapter to work? Here's the circuit for what I'm currently using, and it looks like it's inverter based. I'm not using it, because it's the only one I have and I want to keep it available for other use.
