Subject: problem with sockets

Hi
I've just started using ruby and thought I'd do some experimenting
with TCPSocket and TCPServer

I've got a small problem, in that the program I've written runs fine
on Linux, but runs with a lag on windows. By this I mean that when you
type into the client on std input in Linux, what you type is
automatically displayed.
However in windows nothing happens until you type and send something
else. Like it's caught in a buffer and needs to be flushed. I've tried
flushing the output stream as you would in Java, but nothing seems to
work
If anyone could give me some advice I would be eternally grateful.
I've searched around the net, but to no avail.

Client

require 'socket'
require 'thread'

class Client

  def initialize

    host = 'localhost'
    port = 40000

    s = TCPSocket.new(host, 40000)


    t = Thread.new do

    while(true)

    line = s.gets

	if(line == nil)
	puts("Program is exiting")
	break
	end #of if

$stdout.flush



     puts "Received: #{line}"



$stdout.flush

    end #of while

    s.close

    end #of thread

    while(true)

    puts("About to run stdin")

    line = $stdin.gets

    s.puts(line)


  end #of while
  puts 'QUIT'

  t.join

	s.close

	Process.exit

      end #of con




end #of class


st = Client.new



Server

require 'socket'
require 'thread'

class ServerThread

  def initialize

    t = TCPServer.new('localhost', 40000)


    while(true)

    go = t.accept


    s = Thread.new(go) do |v|


  while(true)


#    data = "none"


    data = v.gets


    v.write(data)



  if(data == nil)
    puts("From inside if")
      self.closeSocket(v)

    end #of if


    end # while

      end #of thread

 end #end of while

    s.join

      end #of constructor

  def closeSocket(sock)

    puts("This is closeSocket")

  sock.close

  end #of method

            end #of class


s = ServerThread.new



Thanks Ian
