Hi guys,

We formatted the syst:stat? command on the Fury GPSDO so as to be  compatible
to GPSCon, that meant following a very rigorous syntax (including the  exact
number of spaces etc), it's not pretty - but works perfectly with  GPSCon.

One note of interest to the group in general: some of our future  products
have a new, very high performance mobile GPS on them that will actually  track
and output 16 Sats and more simultaneously (well, if it could see the Sats  it
would receive more than 30 channels) to GPSCon. A far cry from the 8-sat
Oncore days, and this is causing some grief for GPSCon (not the entire list of
Sat's can be shown by GPSCon without overflowing the page etc). We can't reveal
the GPS details just yet though, please don't ask :)

Seems the web interface of GPSCon works well with any number of Sats  though,
see for example:

http://www.jackson-labs.com/images/gpsstat.htm
(http://www.jackson-labs.com/images/gpsstat.htm)

We are working hard on a set of new products right now, so the ptime  command
changes will have to be put on a slightly lower priority for now
unfortunately. Seems your driver is working well right now though from what I  can gather
in the email thread.

Thanks for your hard work on this,
bye,
Said

I'm not a fan of a the  system:status? command, but it would be nice to get
sat signal strength  from the gps? command tree.

My driver is not ideal, but it works with  what the Fury can do with the
current
firmware.  More to  come.

Those ublox chips are nice, aren't they? ;)
