It sounds like that's the key variable, then.

You can turn on debugging by adding "-D9" before the "-i".  My guess is that
it's hanging on the open, implying a problem in the serial system.

They may have changed the tty device to block awaiting some handshake pin
that's never asserted or they could have a plain ole bug and shipped it
without testing.  We see a lot of that on Linux.   'Security updates' or
power management changes will hose the USB stack for a few weeks and then
they'll start working as mysteriously as they stopped.
