[Xastir] Serial GPS support in Xastir built from Darwin Ports?

[Bernard Tyers]

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:

(kIOMessageServiceIsTerminated) whichInstance 5 temp 1

(whichInstance 6 temporaryInstance 1)
Apr 28 17:28:21 oberena kernel[0]: USA28Xdriver::start (whichInstance 6)


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.
