Hey Joel,

Cool! If its no problem, could you post a summary of what you needed
to do to get SLIP running between your LPC board and Windows XP.
Did you need to add code to LwIP to support SLIP, or was
it in there already?

I've been looking at the Linux side of things for PLIP and SLIP,
and haven't played with the LPC-side yet. Here's my documentation
on SLIP and PLIP from Linux

http://www.ovro.caltech.edu/~dwh/drivers.pdf

I've downloaded the CVS LwIP and contrib directory, but haven't had
a chance to read through it yet. Is there a good design document
giving details on LwIPs implementation? Like I said, I haven't looked
through the source in detail, so there might be something in there,
but any comments would be appreciated.

As for PPP source, in Linux SLIP is a line discipline inside
the tty layer, and so is PPP. If you can't find something that
already bolts into LwIP, that might be a good place to look.

Cheers
Dave
