   It knows more about itself than I.  It's entirely possible that the
version-numbering scheme changed with the name change to PathWay, and
you've probably exceeded the limits of my (failing) memory on this
topic.  In any case, you know what resources I have, and where to find
me, if any of that sounds potentially valuable.

   On the bright side, my dim memory of trying to do anything with UCX
V1.3 suggests that WIN/TCP was far more capable than UCX in the old
days, so I wouldn't feel too bad about using it, even if it's a little
stale.  (That's why we used it, back when.  On the dim side, one
advantage of UCX over the Wollongong/Attachmate product is that, if/when
it worked, you got NFS at no additional cost.)
