I am not sure on hoe to adjust the gps rate but i adjusted the
open cpn to 4800 couse thats what i red you should do somewere.
The thing with the com ports is that as i connect the gps to the diffrent usb ports, i can sea on the propertis of the
sensor that it changes between 1,2,3 and 4 but when i go to the connectiong on the open cpn and try to add connection then i can only choose between 6,7,8 and another one that starts whith
garmin. So obviasly i cannot choose the right comport as it is not an option..
