Funny, even digi message boards won't answer specific questions about IO line passing. Just say check the documentation of the unit you're using. Like that helps. Can't find any sketch that will parse and act upon the Xbee packet I'm sucessfully receiving. The XBEE libray examples don't even read and spit out accurate packet information. I'm sicking of looking at "Hello Moon !" and nothing else. I can see the packet info with X-CtU so I know it's there. Think I'll just have to go rf until better technology comes along.
