Ganesh,

It a work in progress I'm rewriting the file system and httpd example to cope
with the unusual memory model of the 8051.  Otherwise just adding a serial
driver and a timer there are hardly any changes.  I'm planning on adding a PPP
layer once I get the example working properly but SLIP will do for a start.  I
have some PPP code from the PSIStack that is GNU that with major rewrite will
operate I think OK as it is one of the simplest and most complete but there is
still some work to do getting it to handle a single buffer.  I'm also planning
to measure all the optimized C code and see if the SDCC compiler can do a
better job than writing it in a trick fashion (sorry Adam).
I do have some questions for other uIP users.
1. What sort of compilers do you use?
2. Can all on the compilers handle 32-bit longs?
3. Do these compilers have a good preprocessor?

That's about all for now.  If any body wants the source sooner rather than when
I'm finished or wants to offer me a CVS access I'm happy to tar it up for them
or install it into a CVS repository.  This is a home project my day job is
working in a similar environment.


Regards,
Rod Boyce.
