I added the line, but no change...I'm on Windows and tried both the
ioctlsocket(... FIONBIO ... and now the setsockopt(... TCP_NODELAY ...)
u_long flags = 1;
//ioctlsocket(sock, FIONBIO, &flags); // tried both with and
without
setsockopt(sock, IPPROTO_TCP, TCP_NODELAY, (char *) &flags,
sizeof (u_long));
Using my automatic character-sender I discovered a pattern, the ACK is
sent after 14 packetets, ie 7 characters sent and received. The delay is
100ms (as programmed) between each sent characters (with a reply in
less then 10ms) until the ACK , the ACK is sent efter 200ms delay and
then the next character after 100ms more. Summary 200ms of extra delay
each 7 characters sent.
