David,

SNA Over Async is documented in IBM's latest SDLC Concepts publication
(order number GA27-3093-04).  Also, there is a paper out on the APPC
forum on CompuServe which also describes SNA-A.  The paper is located
in the technical papers library section in a file named SNAA.zip.

In summary, SNA-A is an SDLC protocol which drives an async (start/stop)
framing MAC layer.  The async MAC layer is based on an ISO standard
for HDLC over async defined by ISO 3309.
