Thank you. I did what you said and now it appears to be working. I am not sure where I went wrong the first time.

I have a ton of old X-10 modules laying around that I would like to make use of. I have done some searching so if I overlooked a previous topic apologies.

What I am looking for is a way to setup an Arduino Uno with an X-10 Power line converter as a gateway from my Pi to control my X-10 outlets. If there is a better way to do this by simply buying a USB adapter for the Pi I am open to that as well. Any ideas or examples would be much appreciated. Thank you
