I haven't heard any mention of that in ages.  NTPsec dropped that driver (and 
many others).

Which brand of ntpd are you using?  What version?  What distro are you using?

If you are using the classic/Mills ntp package, it's driver 18.  "ACTS" is the 
magic word.  I don't know if your distro was built with that driver.  If not, 
you will have to build from source.  (No big deal.)

Here is the doc for that driver:

There are many copies out there.  This was the top of Google's list.

Plan B would be to use ntpd's shared memory interface.  That's what gpsd uses. 
 The general idea is that you do whatever it takes to get a time offset, then 
drop it into a shared memory slot.  ntpd polls that slot.

If you have detailed NTP questions, we should probably take it off-list.

When you get it working, we expect data.  Extra credit for a pretty graph.

What modem are you using?

How did you decide to go with modems rather than NTP over the internet?
