Sportster Winmodem 33600 & x2/56K - User's manual 47
S6 ! Sets the number of seconds the modem
waits before dialing. If X
n
is set to X2 or X4,
the modem ignores this register and dials as
soon as it detects a dial tone (fast dials). The
range of acceptable values is country-
dependent.
S7 60 Sets the number of seconds the modem
waits for a carrier. May be set for much
longer duration if, for example, the modem is
originating an international connection.
S8 2 Sets the duration, in seconds, for the pause
(,) option in the Dial command.
S9 6 Sets the required duration, in tenths of a
second, of the remote modem’s carrier sig-
nal.
S10 7 Sets the duration, in tenths of a second, that
the modem waits after loss of carrier before
hanging up. This guard time allows the
modem to distinguish between a line hit, or
other disturbances that momentarily break
the connection, from a true disconnect (hang
up) by the remote modem.
While we don’t recommend connecting the
modem to a line with call waiting, if you have
it, you may wish to adjust this setting upward
to prevent the modem from misinterpreting
the second call signal as a disconnect by the
remote modem. A better alternative is to ask
your phone company how to temporarily
disable call waiting (usually *70W). For
example: ATDT *70W

.
NOTE: If you set S10 = 255, the modem will not hang up when
carrier is lost. Dropping DTR hangs up the modem. This
possibility is country-dependent.
S11 ! Sets the duration and spacing, in milli-
seconds, for tone dialing. The range of
acceptable values is country-dependent.
