I just hit reply ;-)

Don't expect anything overnight here - using the
standard RFC terminology - I MAY get around to doing
this port; if I do then of course I SHALL provide
changes/feedback to lwIP ;-)

Thats interesting to know. The ARM 7T Evaluator has
only 512K Flash/512K RAM by default, so I'd need to be
quite frugal.

Yes, its probably the best reference on PPP around. Or
at least, thats what I was told when I was on a
training course given by a commercial PPP vendor.  One
particularly nice feature is that it comes with a PDF
version on a CD too, which is very handy if you want
to search for keywords.

Speaking of books in PDF format, you might be
interested in "Linux Device Drivers", which is
available as a GPL'd online book at
http://www.xml.com/ldd/chapter/book/index.html.

Cheers,
Phil.
