Re: ELKS Networking: TCP/IP?
I have written a SLIP/IP/ICMP/UDP-stack that fits in 2000 bytes program and 36 bytes RAM (not KILObytes) including operating system and device drivers, that fits in a PIC 16F84. So it isn't a problem to implement networking in limited memory. Is it possible to have a look on your code ? Thnks.

So it isn't a problem to implement networking in limited memory. Is it possible to have a look on your code ? I too would be very interested in looking at this code. I suspect it is in assembler, and very PIC specific, but interesting anyway. My understanding is that UDP is a very thin layer on top of IP, and does not require much buffering, whereas implementing TCP is altogether more difficult. Al
