Command Reference
S-Parameters - 95
before continuing with the next dial string parameter.
Range: 1-255 seconds
Default: 50
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
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)*
* In V.34 and V.90 modes, it is not easy to detect a loss of carrier within the S10
time because of the echo of the transmitted signal. It takes over 30 seconds to
determine that carrier is actually lost and then the S10 value comes into effect. In
V.21/V.22 modes, the register operates as described.
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: 9 5 (95 milliseconds)
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.
Range: 0-255 1/50 of a second
Default: 50 (1 second)
