Surely, SiLabs have plenty of info on this - they even have a specific demo kit, don't they?!

There are loads of examples of 8051-based webservers and other TCP/IP-enabled projects - there's even one in the green buttons down the left of this very page!

Here's another: http://www.circuitcellar.com/library/p.../index.htm

And more: http://www.keil.com/tcpip/


Do you mean you want to implement a webserver on your 8051?
Or will your 8051 communicate with a server elsewhere, and people will log-in to that?
