Tom, Thanks very much for the link. I looked at options like this when I first started capturing data from my weather station and it seemed like a little bit of overkill for what I needed. I really only need data from a couple of the serial pins to simply to get the weather data.
I am actually considering getting a serial to USB cable to clean up the connection and prevent mishaps that can occur if an errant dog tail is not kept a reasonable distance away. Cheers!
