Thanks for the comments. I actually haven't spent a lot of time on the
internals of PPP, but I have a basic knowledge of LCP, have been working
with the underlying HDLC framing protocol for many years in other contexts,
and I have a good working knowledge of how CRCs operate. This allowed me to
spot the error quickly, but it took a little while to write up a detailed
and clear enough description of the issue.

Fine with me.
