[hylafax-users] ATDT%s@ trick

[Dmitry Bely <dbely@mail.ru>]

#
# We normally append the "@" symbol to the dial string so that
# the modem will wait 5 seconds before attempting to connect
# and return result codes that distinguish between no carrier
# and no answer.  This makes it possible to avoid problems with
# repeatedly dialing a number that doesn't have a fax machine
# (kudos to Stuart Lynne for this trick.)
#
ModemDialCmd:          ATDT%s@         # T for tone dialing, @ for silence

Can you explain me how this trick is *supposed* to work?

Hope to hear from you soon,
Dmitry
