That's how the network drivers work - the same drivers work in either RedBoot or full eCos with virtually no change. > > BTW, Gary, do you get my query about personal copyright assignment? I was waiting to see what the other maintainers had to say about this. IMO, if this work/effort is purely personal then you can fill out the paperwork that way. As for hard copy, you should sent it - what's a few cents of postage? Send a PDF or FAX to the maintainers if you want to see things happen faster.
