In cast 4, will GLE always be 0 - even if the other end has for example 
reset rather than disconnected gracefully?

The problem we face here is that although we can empirically find the 
GLE values for our current platforms, the possible GLE values are not 
documented!  so we can't be certain we've got it right, that there are 
no unusual cases we simply haven't seen, or that it won't change in the 
future.

I'm happy to with this now, however, since it seems basically 
reasonable, although I do wonder at GLE being 0 for both a reset and a 
graceful disconnect!

Thankyou for your help, Kevin.
