Since you have used your infrared port to control your roomba, I would like to know how you programmed the computer to communicate with the vacuum or to send messages it could understand. Is there software you buy? can you do it with little programming knowledge (C++)? The reason i ask is that i'm interested in getting my tablet pc to control my 200 cd-changer and possibly even home theater system. I have a web page with all of my cds and track listings and I would like to program the pages so taht when i click on a song, the cd changer will go to that disc and track number. Any ideas?
