My "reply to" messages keep being deleted and I'm not sure why so I'm just creating a new one. If this doesn't work, you'll never know. ;)
I want to bring this "full-circle" and let everyone know it was a driver issue or a lack thereof. I am accustomed to macOS having almost all the drivers it needs and it didn't occur to me that I needed a serial driver for the DigiRig serial port. Well, I did and this issue is resolved.
Thanks,
