S7 - Wait Time For
Carrier After Dial,
For Silence, or For
Dial Tone After “W”
Dial Modifier
 Sets the length of time, in seconds, that the modem will wait for carrier before
hanging up. The timer is started when the modem finishes dialing (originate),
or 2 seconds after going off-hook (answer). In originate mode, the timer is reset
upon detection of answer tone if allowed by country restrictions.
 Sets the length of time, in seconds, that modem will wait for silence when
encountering the @ dial modifier before continuing with the next dial string
parameter.
 For US models, S7 sets the length of time, in seconds, that the modem will wait
for dial tone when encountering a “W” dial modifier before continuing with the
next dial string parameter.
Range: 1-255 seconds
Default: 50
S8 - Pause Time For
Dial Delay
Sets the time, in seconds, that the modem must pause when the "," dial modifier is
encountered in the dial string.
Range: 0-255 seconds
Default: 2
S9 - Carrier Detect
Response Time
Sets the time, in tenths of a second, that the carrier must be present before the modem
considers it valid and turns on RLSD. As this time is increased, there is less chance
to detect a false carrier due to noise from the telephone line.
Range: 1-255 tenths of a second
Default: 6 (0.6 second)
S10 - Lost Carrier To
Hang Up Delay
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. When register S10 is set to 255, the modem functions as
if a carrier is always present.
The actual interval the modem waits before disconnecting is the value in register S10
minus the value in register S9. Therefore, the S10 value must be greater than the S9
value or else the modem disconnects before it recognizes the carrier.
Range: 1-255 tenths of a second
Default: 14 (1.4 seconds)
S11 - DTMF Tone
Duration
Sets the duration of tones in DTMF dialing.
Range: 50-255 milliseconds
Default: 95 (95 milliseconds)
