S6 Wait Before Dialing
This register sets the length of time, in seconds, that the
modem must wait (pause) after going off-hook before
dialing the first digit. The modem always pauses for a
minimum of two seconds, even if the value of S6 is less
than two seconds. Waiting for dial tone call progress
features (W dial modifier in the dial string) will override the
value in register S6. This operation, however, may be
affected by some ATX options according to country
restrictions.
Range: 3-7
Default: 6
Units: seconds
S7 Connection Completion Timeout
This register sets the time, in seconds, that the modem
must wait before hanging up because carrier is not
detected. The timer is started when the modem finishes
dialing (originate), or goes off-hook (answer). In originate
mode, the timer is reset upon detection of an answer tone
if allowed by country restriction. The timer also specifies
the wait for silence time for the @ dial modifier in seconds.
S7 is not associated with the W dial modifier.
Range: 1-255
Default: 60
Units: seconds
S8 Comma Dial Modifier Time
This register sets the time, in seconds, that the modem
must pause when it encounters a comma (,) in the dial
command string.
Range: 1-255
Default: 2
Units: seconds
S9 Carrier Detect Response Time
Register S9 sets the time the remote modem's carrier
signal must be present for the local modem to recognize it.
This feature ensures that your modem does not mistake a
busy signal, ring, or voice for the carrier signal. The value
of this register is in tenths of a second. The default value
is 600 ms, although you can change it from 1 to 255. For
example, entering a value 13 means that the remote
modem's carrier signal must be present for 1.3 seconds
for the local modem to recognize it. Setting this value
higher increases the chances the modem will not
mistakenly identify the carrier signal.
Range: 1-255
Default: 6
Units: 0.1 seconds
S10 Automatic Disconnect Delay after Carrier Loss
This register sets the length of time, in tenths of a second,
that the modem waits before hanging up after a loss of
carrier. This allows for a temporary carrier loss without
causing the local modem to disconnect. The actual
interval the modem waits before disconnecting is the
value in register S10.
Range: 1-255
Default: 14
Units: 0.1 seconds
S11 DTMF Dialing Speed
This register determines the dialing speed which is
prefixed for each country.
Range: 50-255
Default: 95
Units: 0.001 seconds
S12 Escape Guard Time
This register sets the value (in 20 ms increments) for the
required pause after the escape sequence (default 1 s).
Range: 0-255
Default: 50
Units: 0.02 seconds
S13 Pulse Dialing Control
This register determines pulse dialing is disabled or
enabled.
ATS13=0
Disable Pulse Dialing
ATS13=1 Enable Pulse Dialing
Range: 0-1
