In the tutorials section of 8052.com, I have posted a tutorial for using an NS8390 ethernet chip for the 8032/52. I didn't see a link on the page so go to http://8052.com/tcpip. I haven't checked out the email address, so if you don't get a response, email as per the email address of this posting. I have included example code that allows you to ping the network card from any machine on the network.

Happy
