			Detect DTR Change: S25 defines the minimum amount of time that DTR has to remain off (that
			is, on-to-off-to-on transitions) before the modem performs the function specified by &Dn
	S25	5	command. A change in DTR that persists for a shorter time than the value specified in S25 is
			ignored by the modem (see the &Dn command).
			Range: 0–255 (1/100 of a second)

			Disconnect Inactivity Timer: This S-register sets the length of time (in minutes) that the
			modem stays online/off-hook before disconnecting when no data is being transmitted or
			received. In data and fax modes, any data transmitted or received between the DTE-DCE
	S30	0	interface resets the timer. In all other modes (except Telephone-Emulation mode), any data
	S30	0	transmitted resets the timer. In Telephone-Emulation mode, S30 is ignored (that is, the modem
			does not automatically hang up the line after a given time delay).
			Range: 0–255 minutes
			0	Disabled

NOTE: An asterisk (*) denotes the factory-default setting.
