Submitted by: Mike Mitchell, supervisor@alb.asctmd.com This is a bulk mport of Mike's IPX/SPX protocol stacks and all the related gunf that goes with it.. it is not guaranteed to work 100% correctly at this time but as we had several people trying to work on it I figured it would be better to get it checked in so they could all get teh same thing to work on.. Mikes been using it for a year or so but on 2.0 more changes and stuff will be merged in from other developers now that this is in.
