I asked this because Hylafax currently treats "BUSY" and "NO ANSWER"
equally. My modem can be tuned to report "NO ANSWER" if the remote does not 
go off-hook after the specified number of rings. So I am going to make "NO
ANSWER" equal to "NO CARRIER" (directly or via additional config
parameter). But I would like to know before if this "ATDT%s@" trick really
makes sense.

Hope to hear from you soon,
Dmitry
