It looks good, but it is only the values under [gps] section that can make your gps work.

Port can be from 1 to 8, Baud can be 4800 or 9600 or 19200 or 38400 or 57600. You have to find the right combination or set it to "auto" and let Primo figure it out.
But primo needs time for it, which can take up to 30 minutes to find satellites, so don't be hasty thinking Primo doesn't find satellites. Also delete the save folder so that wrong values from previous attempts (can be downloaded save folder from different device) does not interfere.
