[time-nuts] NTP and Oncore UT+

Hi Bob,

There seems to be some issue 
with this UT+ that I haven't dealt with.  After a cold boot it does not 
like to start up the comms.  There is apparently some handshake 
procedure to get it all up properly, as the demo version of SynTac's 
software didn't have any problem with getting it going last summer.  I 
just don't know what the proper sequence of probes is to boot it.  Since
 it's been off of battery power for many months, I assume it's going to 
come up mute when I wire it in again.  It always has before when the 
battery is disconnected.  My assumption was that NTP would know the 
secret handshake.  Writing the software to extract the sawtooth is no 
big deal.  It has version 2.2 of the firmware.

>If you have a serial “thing” hooked to the GPS, pulling the sawtooth data out of it is not very hard. They all have some sort of repeating message that contains time / date / sawtooth information.
