shr- GPS howto?

[Michael Sheldon]

You don't need to power on the GPS device yourself, FSO will handle this 
for you when a client requests the GPS resource (and then power it down 
again when there are no longer any clients using it). You'll get empty 
data until the device acquires a fix.

  From what I've read elsewhere it seems important to make sure that 
your time-zone settings and date/time are correct, as it seems FSO uses 
these when getting a fix.

Cheers,
  Mike.
