My guess is that serialport library has no way of knowing if it has any 
data incoming [it has to poll until data arrives?]
If that's the case, then you might could use fork plus some of the 
excellent fork libraries available 
http://allgems.ruby-forum.com/gems?search=fork or you'd need to "fix" 
serialport so that it's 1.9 compatible, and then wrap its read call in 
an rb_thread_blocking_region, so that it allows other threads to 
operate.
