Table 7-1. S-Register Command Descriptions (Continued)
		Carrier Detect Recovery Time: S9 specifies how long the remote modem carrier
		must be present on the telephone line before the modem detects it and turns on
S9	6	DCD. The greater the time duration, the less likely that a false carrier detection oc-
		curs due to noise on the telephone line.
		Range: 1–255 (1/10 of a second)
		Default: 6 (equals 0.6 seconds)
		Lost Carrier Hang Up Delay: For modes V.34, V.90 and V.92, the modem retries
		the connection for S10 plus some base time before hanging up. The base time is 20
		seconds in V.34 and 45 seconds in V.90 and V.92.
		S10 reports the time in 1/10-second units beyond 20 seconds. For example, when
		S10 = 0, the wait time is 20 seconds. When S10 = 100, the wait time is 30 seconds.
S10	14	In V.34, V.90 and V.92 modes, the modem automatically retries the connection for
		45 seconds when S10 = 1–254.
		For all modes, the modem does not disconnect upon loss of the remote modem car-
		rier if S10 is 255.
		Range: 0–255 (1/10 of a second)
		Default: 14 (equals 1.4 seconds)
		DTMF Dialing Speed: S11 specifies the duration of dual-tone multi-frequency (DT-
S11	70	MF) dialing. This register is not used for pulse dialing.
		Range: 50-255 ms
		Default: 70 ms
		Guard Time: S12 is used to specify guard and detect times used for the Hayes and
		TIES escape sequences.
		For the Hayes Escape Sequence, S12 specifies the minimum-delay timer (or guard
		time) before and after the three escape characters that is required for the modem to
		detect the Hayes Escape Sequence.
S12	50
		For TIES, S12 specifies the maximum time limit that must elapse after receiving the
		three escape characters (and no other characters) before sending an OK message
		to the DTE.

Range: 0–255 (1/50 of a second)

Default: 50 (equals 1 second)
