I dabble in home automation and am looking for a framework that would
allow me to monitor and react to serial port events. I'm a long-time
Perl user and if anyone is familiar with POE, that's the type of
framework I'm looking for (an Inversion-of-Control framework where I
have agents running in separate threads monitoring serial ports,
triggering events in the main code). I've perused RAA and seen a few
possibilities, but don't see anything recently maintained. Is there a
good match for the type of thing I'm looking to do?

There are several new home automation technologies available now and
they don't yet have serial drivers, so I figure it would be a good time
to attempt the switch to Ruby. Besides, I'm moving to Ruby, VA next
month, so I figure I'd better start learning the language! :-)
