# Given the above, this works:
readSerial
# But the problem is that rather than just calling that, I want to
thread.
# But the below hangs (I get one line of "Reading line from TTY" --
but only one).
# and while threadTTY hangs, threadGets works fine in the background.
threadGets = Thread.new{watchGets}
threadTTY = Thread.new{readSerial}
threadGets.join
threadTTY.join
# Thanks!
