3.3.3.8 S7 - Wait Time For Carrier After Dial, For Silence, or For Dial Tone After "W" Dial Modifier

S7 sets one of three possible parameters:
1. 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 after the billing delay in answer mode. In originate mode, the timer is reset upon
detection of answer tone if allowed by country restrictions.
2. 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.
3. If enabled by country options in the INF file, 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

3.3.3.9 S8 - Pause Time For Dial Delay

S8 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

3.3.3.10 S10 - Lost Carrier To Hang Up Delay

S10 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)

3.3.3.11 S11 - DTMF Tone Duration

S11 sets the duration of tones in DTMF dialing. This value has no effect on pulse dialing.
Range: 50-255 milliseconds
Default: 95 (95 milliseconds)

3.3.3.12 S12 - Escape Prompt Delay (EPD)

S12 defines the maximum period, in fiftieths of a second, allowed between receipt of the last character of the three escape
character sequence from the DTE and sending of the OK result code to the DTE. If any characters are detected during this
time, the OK will not be sent. Note that sending of the OK result code does not affect entry into command mode. (See 3.1.3.)
Range: 0-255 1/50 of a second
Default: 50 (1 second)
