[En-Nut-Discussion] RE: Re: Trying to work with PPP

[Eduardo Serantes]

Hi Mike and Harald,

I've been developing the CHAP support for PPP this week and it's practically
finished. I'm sure your code is fully tested, so I prefer to use something
working :) Anyway, I can compare your code with the old PPP routines and
with my own code in order to improve the CHAP routines and to provide to
Nut's People a legible code.

Thanks (a lot) and best regards,

Eduardo
