"Linux can do far more natively out of the box then window as its sees the com ports
simply as devices. So it can listen to many devices and do with the data as you tell it too as you have experienced. The issue in a marine environment
is if the putter is a talker it can fail on the hardware
side and it takes quite a while to reset your system once your used to that setup. "
it has happened to me, and is tedious, so what happens in your Linux
box if the GPS
AND OCPN are active with a w/routes each other? this gets through to TCP 2947 and reaches the AP? I am not computerwise expert at hardware
level but I dont like the perspective. Sailias comments/suggestions are sensible in this.
Just out of curiosity what does "wardriving software
" means? sounds scary.
