NMEA extraction AppleScript need help

**Sharkbite86** · 05-02-2006, 05:00 PM

wow im pretty darn lost in all this.... i have been looking over other theads about using google earth as a gps tracker on a mac but i cant get it to work. I think mostly because i cant get my handheld gps to sync with my mac at all... I have this usb adapter from an old palm handheld that i have and i am currently using it to interface my garmin etrex legend to my mac. The only trouble is my mac cant see it at all. you guys know of any software that might will recognize it? Otherwise I guess i will just have to caugh up ~$200 for a gps receiver

...

Not sure exactly what i need to get this to work though (your applescript software) i keep getting this error:

Did you install the driver software for the USB interface? If it doesn't have a driver, then the interface isn't working. Also, what's the event SPA_ISPA reference in your code? It looks like AS isn't getting to the point of talking to the serial driver.

the drivers are os 9 only...

Note the first line in the script:
(*WRITTEN by ZAPWIZARD
Requires GPSNavX available from here: http://osaxen.com/files/serialportx1.0.html
and XML RPC*)

You need to install the serialportx1.0.html and also the XML RPC scripting additions before this script will work. They are easy and free, but required.

If you did that, then you are getting a driver error. But it looks like in trying to execute the command to get a list of the serial ports -which depends on the serialportX scripting addition to do this on Applescript's behalf, it is getting an error. That points to the scripting addition not being installed.

One way to test your GPS is to download GPS Utility. You can set your serial port and watch the data come in from the GPS. If that's working, then you know your GPS is working.

Also, GPS receivers aren't $200. You can get one of the BU-303's for under $100, I'm sure.
