@Timo: many thanks for this hint, this fix resolved my sporadic connection loss issue. I was looking a long time for the reason why sometimes an RST was sent from FNET before the ACK from the Server arrived during FIN procedure.

Yes I see, but why is it segmenting even if the data size is so small that it could fit easily to a packet? And much more important why is the FIN not sent together with data ending and sometimes not at all? (There is nothing in the sending queue) Can you disable this TCP "feature"? ;)

Any idea what could be the problem? Andrej maybe? ;)

Dear, I have a problem with answering HTTP requests. When sent the text “test” as a response to a GET request I see in Wireshark that I get as response the answer separated into 3 TCP segments: segment containing: “HTTP/1.0 200 OK” segment containing: “test” segment containing no data bus finishing the packet with FIN flag. Now my question and problem: Why is FNET separating into 3 segments and not only sending 1 segment with the data + FIN flag? Is there a way to change this behavior? Reason why...
