[QUOTE="Herr R aus B, post: 220523, member: 62807"] We have that rather disgusting but somehow cultic european song contest going on every year, where some I dunno how many million europeans from all over the european union sit in front of their TV sets and watch how mostly terrible singers and bands perform terrible but popular music. then, after some 25 or 30 singers, bands and other creatures tortured the audience with their musical emissions, all brave europeans grab their phones and start a giant phone vote... and than the votings are being presented country by county... that's where the phrase comes from... ;) btw - that is how ABBA became popular - they won that contest in the 70s with "Waterloo". :D Brilliant idea! Ppl will love you! I tested it again a little bit - and yes, there are ill effects :( I dunno how you treat the incoming data, but please don't regard the 0x7E as being part of a single button press! The remote is simply crap and produces random repeats because of the bad button material. You should have these buttons pressed yourself once - than you wuld understand :-) I mean it.
