If you are going to compile it (rather than use whatever comes with your 
system), please use the Release Candidate version from:
  http://support.ntp.org/bin/view/Main/SoftwareDownloads

That's something else.  I don't know what they are.  My guess would be 
something associated with the file system.

It's probably as simple as adding
  server 127.127.26.0
but read the driver26.html page

You also need something like:
  ln -s /dev/ttyS0 /dev/hpgps0


> How do you reboot - apart from of course powering the thing off?

Yes.  Power cycle.

You can sanity check the UTC/GPS by eyeball.  They are 16 seconds apart.

You can clear the E-101 (and get back to scpi) by sending:
  *CLS

Yes.  Power cycle the GPSDO.  At least on the Z3801A, it's stored in flash.  
You only have to do it once.

I think there is a software command to reboot.  I don't have it handy.  
Mostly, I work from the Z3801A manual.  A few things don't work on the 
KS-24361.
