[ECOS] SLIP lwIP and Windows

I'm trying to get SLIP in Windows to talk to lwIP.

Windows connects to the lwIP running in my AT91 EB40a, but 
when I try to talk to the unit itself, things go wrong somewhere.
I've got an ftp server compiled(and seemingly running fine, it just never 
receives any connections).

It is as if the ip traffic is redirected to my development machine instead 
of being directed to my EB40a unit.

I've verified that when I try to ftp in to my EB40a unit, no data goes out 
on the serial port(via portmon in sysinternals.com).
