Hi there,
I have built gpsd from Macports.
I added the GPS via the interface menu (choosing Serial GPS). The
serial port was /dev/tty.KeySerial1.
When I started up Xastir, it hung (main window opens, but black
screen, no maps). I pulled out the serial port and Xastir started
correctly.
As Jason suggested I changed the serial port in use from /dev/
tty.KeySerial1 to /dev/cu.KeySerial1.
I started Xastir with the Serial GPS Interface (4800bps/8bit/No
Parity/1 stop bit) set to activate on startup.
Xastir starts up fine.
It seems to be working, but, every X minutes Xastir crashes and gives
error "Bus Error"
1. I connect the GPS serial port.
Logs show:

2. I start Xastir
3. I check in Interfaces it says GPS port down.
4. I start the Interface
5. My location is updated.
6. 5-10 minutes I look at under View -> GPS Status. I see a valid GPS
information.
7. 5 mins later (or so) Xastir crashes. Logs show error message of
"Bus Error".
I can paste Xastir crash logs if helpful.
Thanks for everything so far.

Could be, but I've never had a permissions problem on a Mac serial
port,
and I've used 'em 8 at a time.
Is there any other application trying to use that serial port for
anything?
You may want to use /dev/cu.KeySerial1 instead of /dev/tty.xzy. Some
folks have better luck with the cu vs. tty. I've never had a
problem with
tty on the Keyspan, but I have with other devices.
Just make sure you don't try to use /dev/tty.xyz and /dev/cu.xyz at
the
same time. I think that's how I managed to make the Mac OS X
kernal dump
core, which never happened before or since. :|
