Pershing Jr." Organization: The Internet Lines: 40 For information on LU-6.2 (a.k.a., APPC), I recommend the following IBM publications (in this order): SC26-4399, "SAA CPI: Communications Reference" Describes the interface between an application program and the end of an LU-6.2 session -- the "Application Programming Interface" (API). It also describes in high-level terms what is actually happening on the session. This tells you how to use LU-6.2 communications, assuming that someone else has implemented it. A well-written manual. GC30-3084, "SNA Transaction Programmer's Reference Manual for LU-6.2" Similar to SC26-4399, although with a lot more detail and including some stuff that hasn't been mapped into SAA. SC31-6808, "SNA LU-6.2 Reference: Peer Protocols" All the grubby details that one needs to actually implement LU-6.2 in a "peer" (PU-2.1) node. A rather large tome. SC30-3269, "SNA FAP: Architecture Logic for LU Type 6.2" The 6.2-specific stuff here is slightly out-of-date as compared with SC31-6808 (which is the "official" reference); however, this includes additional information that you need to implement LU-6.2 in an SNA subarea node (PU-4 and/or PU-5). SC30-3422, "SNA Type 2.1 Node Reference" Information on how to implement a PU-2.1 node (the stuff that roughly corresponds to OSI Layers 3 and 4). A bit on the sketchy side. I don't know of any (non-IBM) books that include any significant material on LU-6.2, although some surely exist... John Pershing IBM Research, Yorktown Heights
