Tom already mentioned http://rubyforge.org/projects/ruby-serialport/, so 
I won't. ;-)

I posted something in this ng recently: rubytalk [92540]
	
     http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/92540

Anyway, the serialport library worked under Win32, after I applied a 
patch to it (which was posted here by Nobu Nakada)

Check
     http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/92265

and the replies to that and my summary at

     http://rubyforge.org/forum/forum.php?thread_id=590&forum_id=227

too (if you're on Win32).

Happy rubying

Stephan
