[UAT] gpsd

[David Brooke G6GZH]

My car pc already had applications using gpsd and I found that the
following allows it to work for this application.

It should work with any path you have permission to create the link but
I used my home directory; just replace <user> with your user id.

In aprs.ini:

[gps]
port = /home/<user>/gps
rate = 4800
type = nmea

Before starting aprs run:

gpspipe -r | socat - PTY,link=/home/<user>/gps,raw > /dev/null &
