I don't have a Windows system to test on but I'm pretty sure that sockets are always automatically opened in binary mode.  On my Mac OS system:

irb> socket = TCPSocket.new("www.google.com", 80)
 => #<TCPSocket:fd 4> 
irb  > socket.binmode?
 => true 

The HTTP protocol requires "\r\n" line endings though so they have to be written explicitly on the binary socket as described in the earlier messages.
