[ntp:questions] ACTS / PTB modem refclock

thank you for your fast reply. I tried exactly that configuration, but 
used the PTB phone number (which works in a test with cu, as described).

When I first did not include the atdt string, ntpd said "no answer" in 
the syslog. When I include the "atdt" I can see no modem activity at all 
and I get zero log entries (reach stays at 0).

I will try again tomorrow morning when I am back in the office and keep 
you posted.
