lwIP? http://www.sics.se/~adam/lwip/ "This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM." Nope. uIP? http://www.sics.se/~adam/uip/index.php/Ports Support listed for Renesas H8S/2472 and ATmega32. "uIP version 1.0 port to AVR with enc28j60 [s]till in early stages of development." Maybe. Have enough projects cooking, DJ? Personally, I'm a fan of UDP, the "underused datagram protocol." :-p - Larry _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
