Hey Alex
I am trying a new modem on my system and some weird things are happening.  Trying to get the gps to come up but its not being shown as available but the mm debug shows there is a port there.  Wondering how I can debug this to get it enabled ?

Any pointers on how to change the gps port to be used correctly ?
