In reply to Earl Shaffer's request, I would suggest the following IBM
publications on LU-6.2 (a.k.a., APPC):

    GC30-3084: SNA Transaction Programmer's Reference Manual for LU Type 6.2
    SC30-3269: SNA Format and Protocol Reference Manual:
                     Architecture Logic for LU Type 6.2

The former is a pretty good all-around introduction to LU-6.2 from the
point of view of a "user" (i.e., a program running in the "application
layer" and using the LU-6.2 services).  I recommend it to anyone and
everyone who comes knocking at my door wanting an introduction to LU-6.2.

The latter (the "FAP Manual") is pretty heavy reading, and tells you more
than you ever wanted to know about the workings of the protocols.  I have
to admit that I haven't read through this tome since about 1983 (before
it was available externally), although the ratio of prose to pseudo-code
has increased since then, so things have to have improved.

There is some general, high-level background on SNA (including a bit on
LU-6.2) in the following two publications:

    GC30-3072: SNA Concepts and Products
    GC30-3073: SNA Technical Overview

All of these are available through your local IBM Branch Office.

Hope this helps...
