S5 (Back Space Character): This register contains the ASCII value of the back space character
(default value is the ASCII 08). Values of 0-32, or 127 may be entered in this register.
S6 (Wait Before Blind Dialing): Contains the numeric value (in seconds) for the time to wait
before dialing the telephone number after the line has been taken off-hook (default is 2 seconds) if
blind dialing is enabled (blind dialing is supported by Result command X0, X1, or X3; Result
commands X2 and X4 disable blind dialing; and S6 is irrelevant). This provides time for the central
telephone office to detect the off-hook condition. Values of 2-255 may be entered in this register.
S7 (Wait for Carrier After Dialing): Contains the time delay (in seconds) between dialing and
responding to the incoming carrier signal after initial connection (default is 30 seconds). If a carrier
is not detected within the delay time, the modem hangs-up line and a "NO CARRIER" result
message or "3" result code is returned. Values of 1-255 may be entered in this register.
S8 (Delay Duration for Comma): The value in this register determines the time delay generated by
a comma (,) in the Dial command string. Default is 2 seconds, while the range is 0 to 255.
S9 (Carrier Detect Response Time): Contains the time value (in 100-millisecond intervals) that a
carrier signal must be present before the modem recognizes the carrier and issues a carrier detect
(default is 6 [600 milliseconds]). This prevents a ring or a busy signal from being mistaken as a
carrier. Values of 1-255 may be entered in this register (100 ms to 25.5 seconds, respectively).
S10 (Delay Between Lost Carrier and Hang-Up: Contains the time delay (in 100-millisecond
intervals) between the loss of the carrier and the when the modem hangs-up on the line (default is 14
[1.4 seconds]). Values of 1-255 may be entered in this register (100 ms to 25.5 seconds,
respectively).
S11 (DTMF Tone Duration): Contains the duration (in milliseconds) and spacing of tones in Dual
Tone Multi-Frequency (DTMF) dialing (default is 70). Values of 50-255 may be entered in this
register. This value has no effect on pulse dialing, which is fixed at 10 pulses per second.
S12 (Escape Sequence Guard Time): Contains the guard time (in 20-millisecond intervals)
required prior to and following the escape sequence (default is 50 [one second]). It dictates the time
that escape sequence (+++) must be entered. Values of 20-255 may be entered in this register.
S25 (DTR Delay): Specifies the time (in 10-millisecond intervals) that a change in the DTR signal
(on or off) must maintain before the modem recognizes it (default is 5 [50 milliseconds]). Values of
0-255 may be entered in this register (0 to 2.55 seconds, respectively).
S26 (CTS Delay): Specifies the time (in 10-millisecond intervals) that the modem waits after a
transition of an incoming RTS signal before asserting the CTS signal (default is 1 [10 milliseconds]).
Values of 0-255 may be entered in this register (0 to 2.55 seconds, respectively).
