Command	Default	Description

		Sleep Mode Timer: S33 determines when the modem enters sleep or power-down mode.
		When enabled (S33 ≠ 0), the controller enters sleep mode whenever the modem has been
		inactive for a user-programmable time delay (S33). The modem is considered to be in an
		inactive state when:
		• No internal processing is being performed;
S33	10	• No activity occurs between the host and the modem within a
S33	10	specified time period;
		• The modem is off-line.
		The modem exits sleep mode whenever the host reads or writes to the
		modem or when a ring signal is detected.
		Sleep mode is disabled by setting S33 to ‘0’.
		Range: 0–90 seconds
