I see. The problem is that for time reasons the port that I've set up is done
very poorly. It uses the raw api. It is nothing but a single thread that

That can't work: input processing is not called from your while(1) loop
and tcp_write/tcp_output thus still racing with input processing (e.g.
TCP ACKs).
just to keep the pcb variable valid.
I'm not sure I understand this...
I know this is very bad but I
didn't have time to port it properly.
Doing things bad is never a good idea... Event worse if you know it's bad!
That being said do you think there is a way to make tcp_outout flush? Some
kind of a workaround... I'm pressed for time.
At least I wouldn't know of any.
