Well, permissions are a good start... And minicom was running as root...
but Xastir still locks up when running as root also.

The port by default is set crw-rw-rw-, o: root, g: wheel, most likely
because any user under MacOS could need access to the serial port.
Remember that it's a consumer-oriented OS...

It seemed like I had some luck, somehow, for a bit. It seemed to be able
to open the port and send commands, but wasn't receiving anything back.
But this disappeared after a reboot and I'm back to the original state of
locking up on port open again. I set debug level to 2, and it locks right
after the port open line, before anything was even sent to it.

Unfortunately, I don't have another USB to Serial adapter to try. I have a
device that makes use of a FTDI USB to Serial chip, and I've never had a
problem using that device with the software that came with it, but it's
not a plain USB to Serial adapter, and that software isn't X11 either.

Any other thoughts or anything I can do to get more information on the
problem?
