I stumbled accros this tonight and thought this may be of some interrest to
a few of the DJGPP developers who also are involved in the embedded area.
Sorry for sending this if this is a waste of bandwidth. I have not played
with this yet.

The sales blurd:-
lwIP is a small independent implementation of the TCP/IP protocol suite that
has been developed by Adam Dunkels at the Computer and Networks
Architectures lab at the Swedish Institute of Computer Science as part of
the Connected project.

The focus of the lwIP TCP/IP implementation is to reduce the RAM usage while
still having a full scale TCP. This makes lwIP suitable for use in embedded
systems with tenths of kilobytes of free RAM and room for around 40
kilobytes of code ROM.

lwIP features:

  a.. IP (Internet Protocol) including packet forwarding over multiple
network interfaces
  b.. ICMP (Internet Control Message Protocol) for network maintenance and
debugging
  c.. UDP (User Datagram Protocol) including experimental UDP-lite
extensions
  d.. TCP (Transmission Control Protocol) with congestion control, RTT
estimation and fast recovery/fast retransmit
  e.. Specialized no-copy API for enhanced performance
  f.. Optional Berkeley socket API

lwIP is freely avaliable (under a BSD-style license) in C source code format
and can be downloaded from the download page.
