How can I Network using a microcontroller

I have a microcontroller and I want to make a connection with a lan
card (a pc on a lan) using TCP/IP. I think to use the lan card IC to
control the protocol, but I need to write a driver for it on my
hardware. Can anybody help me to write the driver. I am experinced
(almost) on 8051 microcontroller.

Thanks,
Omid.

Not only will you need to write the packet driver, but you'll have to
write the TCP/IP stack, too.

If you ask for "help to write the driver", then you probably need to
hire a programmer. If you have *specific* questions, ask post them to
the newsgroups.

Rabbit makes an 8051 development board complete with 10 base-t ethernet and 
includes a TCPIP stack with source - I think.

Check out Digikey

I have wondered about the same thing; or
minimum effort to add TCP/IP...

HAs anyone experience with Wiznet modules, like the
IIM7010A ???

Get the book "TCP/IP Lean, 2nd Ed", by Jeremy Bentham, CMP Books. 
Nice discussion of how to implement a really small TCP/IP stack.  He
doesn't provide an 8051 implementation, but his C code will work on a
PIC.

You'll need a tcp-ip stack.  You might consider using embedded Linux
or uCLinux.

You can also have a look at

The PICDEM.net demo board from Microchip and TCP/IP Lean go hand in
hand. There is a also an Atmel solution that my former colleague did.
If i had to implement it, i'd probably purchase a picdem.net board and
try to reuse the code.

With the Atmel ATWEBSEG32 module you can connect your
8051 using the Serial port and do not have to know anything about TCP/IP.
The module has the Wiznet and an 8051.

or eCos.

I found a one-chip solution that looks like an exact fit for what you
want. Look at www.maxim-ic.com

The DSC80C400 is an 8051-based microcontroller that has a MAC
peripheral built in the chip. It also comes with the TINI TCP/IP stack
in ROM. I don't know how to use it though, but for an 8bit chip, this
is something i'm definitely going to be looking into now.
