An old thread, but I have found an easy solution to using gpsd and navigation software at the same time.
and just point your navigation software to com1. com1 will be created by socat, so if it already exists, delete it or use com2.Code:gpspipe -r | socat - PTY,link=/home/ravenous/.wine/dosdevices/com1,raw
You can find the solution here. Someone there mentioned this thread, so I thought I'd post it here too.
