Hi Horst,

>Yes, I'm porting lwip to Motorola 68302 (big endian too).

Thanks. You probably have the nearest architecture to my own, which is uses
plain old 68000 code, running on >=68020. Would it be possible for you to
send me your lwipopts.h and compiler options (privately)? Thanks a lot.

So using SLIP might be part of my version 0.5 problems.

>I'm using to latest cvs-sources! TCP, UDP, ICMP, httpd - all works.

Great.

I first used the >0.5 cvs-sources (same problem), but went back to the 0.5
release. I thought at least ICMP should work with that one.

Yes, I already avoid this. Thanks a lot for your ideas.
