Update on FC4, CXO, GPS/topo maps, etc.

Turns out that huge IF was wrong. I got onto the gpsd list --
gmane.comp.hardware.gps.gpsd.user -- and asked; here is one reply :

He's right about what I want -- no, need. I'm not going to try to scramble
up and down pathless slopes of the Blue Ridge Mountains, at my age, with
a laptop, in addition to a GPS and a shotgun (in season) or a
wanderstaff. So passes the glory of that hope.

There remains the possibility of putting symlinks into .wine
somewhere, so that they tell Fedora what to feed to the GPS to make
it think it's listening to com1 or com2. (I tried it in each bottle
in .cxoffice, with the help of the grc people, and it didn't work.)
Kibitzers welcome, particularly as to which .wine, my user's or root's ...

There is also another suggestion from the gpsd list "Grass and qgis
are your open source choices.  Start with qgis and let us know where
you get."

I looked at grass once, a year or three, and was totally flummoxed. Qgis
is at http://qgis.org/ -- I'll look, but I'm not sanguine, particularly of
my linux competence, nor my cartographic competence, nor  ...

Stay tuned.
