Sorry Jim, I should have made it clearer - in this context "application" is a
term that the uIP code attributes to functionality such as SMTP, Telnet, ARP,
etc. and the code that invokes that functionality.

I think I understand most of it.  The major thing that has me puzzled is how to
declare the "state" (context) area size.  As far as I can tell you can only
declare one size for all applications.  The data area is set aside in the block
uIP uses to store its context for each connection.  So I assume I have to tell
uIP that the context size is the max of the applications I'm using (SMTP & Web
Server).  I'm unclear on it because I can't find an example that uses multiple
uIP "applications" in a single processor image, only examples using a single
application or multiple applications each having no saved context.

My search continues ...

Cheers,
