Subject: Poll STDIN for waiting input on Win32

How can I determine if there's input waiting on STDIN before calling
gets?  This code doesn't do the trick:

----

while true
  r, w, e = select [$stdin], [], [], 1
  
  if r and r.include? $stdin
    puts "READY TO READ!"
  end
end

-----

Apparently, r always includes $stdin, so it just continuously prints
"READY TO READ".
