Ubuntu

GPS is serial and Viking is looking for a USB port

Asked by Murray Peterson

I run Ubuntu 13.04, and I have a Garmen GPSMap 76C which has a serial connection to the computer. I downloaded Viking 1.3 and tried to acquire data from the GPS. In Viking the communications protocol is Garmin serial/usb, and the port is called usb. There is only one selection for port. Since my GPS is connected to the serial port, I believe I need to:
a) make Viking recognize a serial port as well; or
b) make Ubuntu recognize the serial port as a USB port when Viking searches for a device.

Can anyone help?

Can anyone suggest another mapping software that would work? I am not tied to Viking in any way, and would be happy to try another.

viking should have a gpsd option to get data from the gpsd daemon. Install the gpsd package if needed. Start the gpsd with the device you want e.g. gpsd /dev/ttyS0 for the first serial device.
Can't recommend the Ubuntu version of gpsdrive (pre 2.11), it does not talk to gpsd. Downloading 2.11 is possible, and works.

Thanks. I have gpsd 3.6-4 installed and stared gpsd as you suggested
below. Still the same results. Is there a way I can verify that the GPS
is found by gpsd? Can I ping the GPS?

You can start gpsd in debug mode, and get interesting output -- for example for the rfcomm device I used for bluetooth connection to my gps (use your serial device when you try it):

sudo gpsd -n -N -D2 /dev/rfcomm0

#gpsd: launching (Version 2.37)
#gpsd: listening on port gpsd
#gpsd: successfully connected to the DBUS system bus
#gpsd: running with effective group ID 0

Also, install xgps and you can see which satellites are being used by gpsd.

Can you help with this problem?
