Ok, you've convinced me that I should seriously consider Ethernut.  Since I've
got my hands full with SW development without adding board development.  Does
someone have a board made up with the components to support PPP?  Or, can I add
a second RS-232 port (via the expansion connector?) to one of the Ethernut
boards so that I can support LAN and PPP (PPP near-term, later switching to
10-BaseT when I have it available)?

I note that one of the boards supports a second serial port but it is
half-duplex only.

In scanning the Ethernut site (http://www.ethernut.de) so far I only find in the
SW manual mention of PPP support but nothing on how to configure/accomplish
this.  Can someone point me to something?

I think I can manage the SMTP and POP3 stuff ok ...

Thanks for the help ...
