"My company project is to interface the existing Lan card to the 8052 microcontroller. What should i do for this. "

Hope your Boss has no chance of reading this lest he should start wondering dangerous things..

"Please mail me the project files for this or any susggested URL of the previous project. "

Maybe I am dull. But I really wonder how one expects to get a useful reply to such a vague question. What is the interface supposed to do ? What is the human inteaction in this project ? What LAN card ? Which derivative of 8052 are we talking about ? With respect to the card where or how far away will the 8052 be ?
