I'd have to agree when I read it again.
I am in over my head trying to debug why this doesn't work with a the
Windows incoming connections PPP server, hence jumping to conclusions.
Is this feedback helpful or just frustrating? :-)
I presume Windows wants support for CI_CALLBACK. I'm not using it, so
why Windows asks for it, I don't know.
I didn't find any CI_XXX for 17,19,23 so I don't know what they mean.

Bad wording from me.
Without the changes in the last message, the link was immediately
terminated by the Windows PPP server.
I'm not quite sure where to go from here.
