About two weeks ago, I actually decided to read one of the slick propaganda pieces that Apple likes to shower us with. It was called "The Advantages of AppleTalk Phase II". It turns out that it is a VERY nice pamphlet and is filled with interesting and relevant information. What puzzles me is why it has a paragraph that states: (roughly quoted from memory) "System software 7.0 will contain new LocalTalk drivers that implement all of the features of AppleTalk Phase II except for extended addressing". The brochure goes on to state that "some software will eventually require that you run AppleTalk Phase II even on non-extended LocalTalk networks". I asked our local Apple Canada head System Engineer if you knew anything about this. He didn't have a clue. The Apple Internet Router DOES let you enter multiple zone names for a LocalTalk segment (for future compatibility????). Is this a case of the marketing people not clearly understanding the intentions of the engineering people or what? -- +----------------------------------------------------------------------------+ | Pascal Gosselin | Internet: P.Gosselin@CAM.ORG Applelink: CDA0585 | | Gest-Mac Inc.

He didn't have a clue. As far as Phase II functionality is concerned, it is my understanding that the only new feature of the LocalTalk drivers is the best router algorithm. Previously, the LocalTalk drivers would use the router that they last heard from, regardless of whether it was the most efficient one to use. The newer drivers keep track of the number of hops to a given net and the best way to get there. Phase II AppleTalk also allows the use of the newer NBP calls, making life easier for the programmer. The recent ADSP example in develop requires AppleTalk 53 or later for this reason. There may be other new programmatic features of 53 and later - this is the only one that I can remember. ______________________________________________________________________ Stephan Somogyi No. No. No. I'm NOT with MIS.

There's also the transition queue that let's your programs hear about it when the MPP driver is opened or closed. (Why oh why did they put a C interface on this thing! What a pain from Pascal, at least C routines can be declared as using a Pascal calling sequence) Let's see, also PGetAppleTalkInfo, sort of a SystemInfo for AppleTalk. -- michael -- Michael Peirce -- outpost!peirce@claris.com -- Peirce Software -- Suite 301, 719 Hibiscus Place -- Macintosh Programming -- San Jose, California 95117 -- & Consulting -- (408) 244-6554, AppleLink: PEIRCE
