LAN Manager "out of the box", if from IBM or Microsoft, does indeed
use NetBEUI - unfortunate, since it is a non-routable protocol.  Considering
that AT&T has linked with MS, and AT&T uses TP4 (lower four layers of
OSI), and since about 10 vendors are behind this linkage, I would expect
to see more and more TP4/OSI networks being build.  True, the MAP/TOP
spec isn't full OSI, and implements an AFI of 49 (local), which is not
GOSIP compliant, TP4 CLNS *is* a true OSI standard...just not exactly
what the Government wants.  I might hasten to add that it is quite easily
configurable to GOSIP specs as regards the Network Layer.
