[En-Nut-Discussion] error of compiler

[ZIP]

Thanks Ole, i will read this. But for me now it shouldn't be the problem.

The thread starts with NutTcpAccept() .. so the loop isn't running and 
it's waiting for an incomming connection. I do have there some 
NutNetSleeps().

So I can't see why it should be blocking other threads.

I'm attaching the code of this thread...

best regards

Petr
