Default: 50
11.9 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
11.10 S9 - Carrier Detect Response Time
S9 is supported for backwards compatibility only. No value can be written. Responds with default
value.
Range: 6 tenths of a second
Default: 6 (0.6 second)
11.11 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)
Note: For Call Waiting detection, if the modem is set to US country code and S10 >=16, then the
modem will detect the Call Waiting tone and hang-up the line. If S10 <16, the modem will
not detect Call Waiting tone.
11.12 S11 - DTMF Tone Duration
S11 operation is country dependent.
1. For US models, S11 sets the duration of tones in DTMF dialing (has no effect on pulse
dialing).
2. For W-class models, S11 is a country parameter loaded by ConfigurACE.
Range: 50-255 milliseconds
Default: 95 (95 milliseconds)
11.13 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. Sending of the OK
result code does not affect entry into command mode.
Range: 0-255 1/50 of a second
