I get a lot of *noise*; the problem is to dig out the information... ;) >> 2) Are there more buses I like theese above? >Yes, an awfull lot, including variants of the above. OK, IĞll clarify myself: I am not interested in the higher layer protocols, as we have some odd requirements. What we really are looking for are the chips, controllers etc, and possibly the lowest error detection and correection etc layer where included (like CAN). We could roll our own, but if there already exist good chips, why bother. And for established standards there are also nice debugging tools :) Especially I am looking for Ethernet specification. Who owns Ethernet? (I think i shold look there) whatever is www.ethernet.org ?! Somebody who has regged teh name to earn money when selling it? Or is this really the site? Where to get the key in that case ?? PS If somebody has replied to this subject during the last hours, please repost, as I got unsubscribed by Jory as I have an iname account. (You did the right thing though, Jory!)
