I am afraid, RDoc won't have an exhaustive list of these constants.
However, for all such purposes, I have Richard Stevens book on network
programming book and you can find them listed there.

As for disabling naggle algorithm you can use:

t_sock_addr = Socket.sockaddr_in(port,ip)
t_socket.setsockopt(Socket::IPPROTO_TCP,Socket::TCP_NODELAY,1)

Also problem you mention shouldn't have anything to do with flush or
naggle algorithm.
Probably, your server is using newline as message separator in which
case. But this is just a wild guess.
