This looks to be OK to me?

I read in this topic that I should run the command stty -a -F yourGpsDevice but I get the error: sh: stty: not found Do I need to install something to be able to run this command?

In your program I'm using the following options:

Choose Usb GPS: /dev/bus/usb/001/023

Choose GPS device speed: 4800

Replace internal GPS : ON

Auto-enable location provider: ON

SiRF GPS: Don't sue SiRF Options

I installed aLogcat and got the following output:

This looks like GPS data to me? Are there any more steps I can take to debug if it is working?

I'm using GPStest to check if it works, but I get no data.

Thanks in advance, I really would like to get this to work.
