OTOH, I don't remember ever using one... -- Thanks, Fred.

There is a PIC with build in Ethernet controller but in one of those tiny packages. I use the 18F14K22 PIC and a ENC28J60 controller, both DIL, making it much easier to put together a quick veroboard thing. That iPIC TCP/IP stack sounds interesting though, as some services, for example Vodafone, seem to block UDP packets one way, probably stateful firewalls used against VOIP.

I'd love to try it out, but I'm an AVR guy - I wonder how difficult it would be to port the code to use on something like an ATMega168.... |
