cgps timout with NAVILOCK NL-402U (no fix)

[Nechtan]

The gpsd starts at boot and gpsd output shows that the device is
working. (see output below)

The problem is, as long as the device doesn't have a fix, cgps gets a
timeout.

<user>@<machine> ~ % cgps
cgps: GPS timeout

When the device has a fix cgps (and other software) show data and
recognize the device.

[Nechtan (seelig)]

Actually this is not a bug, but expected behavior. cgps times out when the device sends no valid data.

So this bug can be closed or whatever, because it won't 'fix'.

Sorry for the inconvenience.
