An 8051 is severly underpowered, and under-RAM'ed, to handle even low speed ethernet let alone multiple sockets. -- Regards, Albert ---------------------------------------------------------------------- AM Research, Inc.

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: http://www.lantronix.com/products/eds/xport/index.html http://www.digi.com/products/embeddeddeviceservers/digiconnectme.jsp

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

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.> > > > >> You'll need a tcp-ip stack. You might consider using embedded Linux > >> or uCLinux.> > > > >or eCos. > > > > On an 8051 ?

Linux will not run on an 8051. -- Regards, Albert ---------------------------------------------------------------------- AM Research, Inc.

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 : tkproj@inwind.it Bye From Italy Roberto Vescovi
