I don't know about that "old dos door game", does it read from
stdin certainly?

Separating select call would not be nice.

    while ios = select([pipe, @socket])
      r, * = ios
      if r.include?(pipe)
	char = pipe.getc

	puts "char: #{char}"
	@socket.write ?\r if char == LF
	@socket.write(char.chr)
      end
      if r.include?(@socket)
        puts "socket hit"
        char = @socket.getc
	puts char.chr
        pipe.putc(char.chr) if char
      end
    end
