	Yes, check out: http://www.amresearch.com:2005 for a preview of our
8051-type webserver/microcontroller.  At the moment we're experimenting
with adding CGI and POST operators but both the circuit and source will be
released under the LGPL license by March 1, 2004.

	Normally, yes, you would have to but recent components like the W3100A do
much of the toil in h/w.  An 8051 is severly underpowered, and
under-RAM'ed, to handle even low speed ethernet let alone multiple sockets.

This can be a very big effort, especially the TCP stack.

See http://www.edtp.com for cheap LAN prototyping cards and C code.

Google on 8051 and one of these controllers: NE2000, RTL8019AS, CS8900A,
91C111,	AX88796, DM9000

Best, look at one of these turnkey solutions that translate a serial
interface to TCP:

On an 8051 ? You must be kidding :-)

No, IMHO Rabbit uses their own CPU's which resemble more a Z80 than an
8051. 

While I havent used this part so far, this might be a good candidate
for what you want since it includes a MAC and a complete TCP/IP stack.
See:

I'm not sure if we're talking the same thing, if you want netowrking like
TCP-IP or you just want the processors to talk to each other. If the later
is true the 9 bit serial mode works great for that.

	The original point was an 8051-web server.  Linux will not run on an 8051.

There is a limited TCP/IP stack called emBetter for HC12, but AFAIK it
is mostly in ANSI-C.

Hi Omid.

I develope a fantastic IPC@CHIP Beck board based on Beck SC12 Chip
(186 with Ethernet/CF socket/two serial port, I/O, Sja1000 CAN
controller ecc)

You can debug and program chip with free Beck Tools (Borland C++ 5.2
with special Turbo debugger) with 10mbit ethernet connection

You can develope web server, Tcp remote client/server control, Ftp PPP
Email connection ecc..

for price and more information send email at : t...@inwind.it
