Thanks for that,

I have ordered the ALFATSD board but it'll be a couple of weeks to get to New Zealand. I am planning on using UART in text mode since my application is a simple serial logger.

I've also looked at the proton basic stuff and it looks helpful but I won't know how helpful until I dive into the actual project.
I was hoping you or eoasap had a bare bones PBP program to get me started since I'm not using the proton development board.
Perhaps when I get my chip I'll cobble one together and may re-post if I hit a brick wall. I'm still a bit of a newbie but have had pretty good sucess with serial comms on these chips already. the only unkown is writing this serial data to a text file. Thanks again for the timely reply.
