Holy moly, I am glad I found this topic.
I’m a coder, and used to be a major data comm coder geek. I always wondered how Pal’s protocol worked. You ask a Pal person for info on that or their API’s they get borderline unpleasant and act like you are scum, sheesh.
Very interesting stuff. Might pursue this further sometime with a sniffer and see what else is going on.
