[En-Nut-Discussion] TCP_NODELAY

[Harald Kipp]

Hi Emjay,

NutTcpSetSockOpt() can only handle

   TCP_MAXSEG  Maximum segment size
   SO_SNDTIMEO Socket send timeout
   SO_RCVTIMEO Socket receive timeout
   SO_SNDBUF   Socket output buffer size

But Nut/Net delays output segments a very short time only. I assume
that your problem is caused by a missing flush of the socket stream.
Use fflush(stream).
