Subject: Detecting Arrow Keys

Hey all,

In short, I'm looking to, through an STDIN/OUT console interface,  
detect which arrows keys have been pressed. Here is everything I have  
so far...

PRGM A = http://pastie.caboo.se/133393

using PRGM A, I have been able to detect all key combinations  
necessary for all of my motives - except, of course, for this one.
Let's go through a basic run-through:
$ ruby single_character.rb
    Enter one character:  27			# UP-arrow
$ ruby single_character.rb
    Enter one character:  27			# DOWN-arrow
$ ruby single_character.rb
    Enter one character:  27			# LEFT-arrow
$ ruby single_character.rb
    Enter one character:  27			# RIGHT-arrow

Hmm... Something's not right here... Why are they all the same?

So that is as far as I have been able to get. OH! My goal:
	Write a pure ruby Readline alternative.
	--> (Actually, just emulate history)

Yes, I understand there is a Readline for windows, but really,  
detecting this is harder for the programmer, and thus less work for  
the user. Probably me.

Is there some hidden method that I am not realizing?


Thanks,
Ari
