I don't know the answer, but quite interesting topic.

BTW, what language are you using with the Microcontroller?

You can use:
- an Ethernet chip like ENC28J60-- PHY+MAC http://tuxgraphics.org/electronics/200606/article06061.shtml and connect it to uC on SPI bus - I know there are libraries for many uC to use ENC28J60, so you don't need to write the code for the server from scratch;
- buy this http://www.ethernut.de/ - i know someone who used it and it worked great;
- just an ARM processor with Eth ports.

I dont kow why you reposted the same question

you use serial coms from the micro to a driver that talks to lan on an ip

the problem is that a micro
has to build the whole ip stack and lan handler
before it can use lan exclusivly

so use serial to lan driver

then coms.. is very much easier

if you want to learn how lans guts work your going the right way

a tip is set up the drivers for serial
its no matter if the software times out
the driver remains ... active as set

so... download it and give it a try
look in your other post

Very Happy

thx Eugen_E
i have viste your links.... it much helpful to me.
but wht in case of http://www.ethernut.de/...... it cost much. there are so maney other SBC like from rabit pro etc. but i thinking what it i implement some thing with Ethernet interface chip RTL8019AS wih pic micro and use UDP protocol .... coz wht i thnik its easy to emplement , as my system is in same lan data ACK is not necessery....or it can achive with some fixed packet 2 way communication???? any body hav any idea pls coment thx in advance
