Could someone show me a sample how to flush the socket sending buffer? Thanks a lot.

I have called the setsockopt() to set no delay after connecting like
this way:

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('192.168.10.1', 21980))
s.setsockopt(socket.SOL_TCP, socket.TCP_NODELAY, 0)
s.send("(e-mail address removed)\n")
s.send("(e-mail address removed)\n")
......

but still, the server can only receive the first line, and keep
waiting for the second line. So, in my mind the second line is still
in the sending buffer, and not reach the server side.

Any hints would be appreciated.
