Since I have virtually no LAN programming experience I would welcome *any* comments on the following problem: We want to interface a Macintosh II to Elscint APEX machines The LAN protocol for the APEX conforms to the following standards: data link IEEE 802.3, IEEE 802.2 LLC Class 1 network Class 3 Connectionless Network Services ISO standard 8473 protocols the apex configuration implements the "NULL2" service of the network layer utilizing map 2.1 subnet and area addressing (restricted to single subnetwork operations) transport ISO 8073 Class 4 protocol for virtual circuit services The questions is: Is it possible to use a Macintosh EtherTalk card for this connection? Is this card (and/or its driver) compatible to IEEE 802.3 - that is, does it suffice to assemble a packet in the correct format (Preamble, SFD, DA, SA, LLC Data length, LLC Data, Pad & FrameCheck) and then invoke the ETCall routine (after having installed an appropriate listener for such 802.3 packets)? I guess this is an issue since IEEE MAUs define additional signals in respect to EtherNet, like Jabber. If the EtherTalk card is a "no-no", is there any product which will supply the needed functionality? Again: *any* comments, hints, pointers, etc. are welcome; Thank You for your trouble... paolo -- paolo petta (...cernvax!tuvie!ai-vie!paolo) (from bitnet: paolo%ai-vie.uucp@cernvax) (from US: paolo%ai-vie.uucp@uunet.uu.net)
