I hacked in an exception stack trace:
```
exception details Traceback (most recent call last):
File "/usr/share/weewx/weewx/engine.py", line 107, in setupStation
self.console = loader_function(config_dict, self)

fcntl.ioctl(self.fd, TIOCMBIS, TIOCM_DTR_str)
IOError: [Errno 22] Invalid argument
```
An invalid argument? Is this a library problem, or a permissions problem,
I'm not familiar enough with python to know exactly why it's upset here,
but it seems to be dying in the library, not in weewx... maybe?
