Greg,

Unless somebody else changed it, the ACTS driver refclock_acts.c that 
left me always did require the full explicit Hayes string. If the only 
message was "acts: no modem", the modem did not respond to the 
MODEM_SETUP string. I have not yet found a modem that does not respond 
to that string, but this might be the first.
