AT Commands, Cross-Referenced to Front Panel Options (Continued)

AT	Parameter &
Command	Option	Description
AT&W2	=2	Save changes to Option Set 2.
AT&W3	=3	Save changes to Option Set 3.
AT&W4	=4	Save changes to Option Set 4.
	Clock	Clock
		Sets modem timing and applies to synchronous applications only. For most dial applications,
		use internal timing.
AT&X0	=Internal	The modem uses internal timing; timing signals are passed on EIA/TIA 232-D Pin 15 (V.24
		circuit 114). Internal timing is used for most applications.
AT&X1	=External	The modem uses external timing; timing signals are passed on EIA/TIA 232-D Pin 24 (V.24
		circuit 113). Internal timing is used for most applications.
AT&X2	=Loopback	The modem uses loopback timing; timing signals are passed on EIA/TIA 232-D Pin 17 (V.24
		circuit 115). NOTE: This selection is not available in SDC mode. If you select loopback with
		SDC mode enabled, the modem uses internal timing instead.
	Power Up In	Power Up In Option Set
AT&Y0	=Old	When you turn on the modem, it automatically uses the last saved option set.
AT&Y1	=1	When you turn on the modem, it automatically uses Option Set 1.
AT&Y2	=2	When you turn on the modem, it automatically uses Option Set 2.
AT&Y3	=3	When you turn on the modem, it automatically uses Option Set 3.
AT&Y4	=4	When you turn on the modem, it automatically uses Option Set 4.
	Enter Phone #	Enter Telephone Numbers (where n=1-9)
AT&Zn	=1–9	Lets you store up to nine telephone numbers in the modem’s “address book” of up to 50
		characters each. To enter a number into the address book: enter the AT&Z or AT*CN
		command, the telephone book address (1-9), a comma, and the telephone number to store. For
		example, to store the number 1-222-555-444 in memory location 3, enter:
		AT*CN3,12225554444<CR>
		If you enter AT&Z or AT*CN without specifying a memory location, the modem stores the
		number in address 1. If no telephone number follows AT&Z or AT*CN, the specified memory
		location’s telephone number is deleted. NOTE: When dialing telephone numbers, you can
		include dial modifiers to instruct the modem how and when to dial a call. Refer to Table A-4.
	Answer	Answer
AT*AA0	=Manual	An incoming call must be answered manually.
AT*AAl	Answer=Ring #	The modem automatically answers an incoming call after the first ring.
	1
AT*AA2	=Ring # 2	The modem automatically answers an incoming call after the second ring.
AT*AA3	=Ring # 4	The modem automatically answers an incoming call after the fourth ring.
AT*AA4	=Ring # 8	The modem automatically answers an incoming call after the eighth ring.
AT*AA5	=Using S0	The modem automatically answers an incoming call according to the setting of S-Register S0.
	Adaptive Rate	Adaptive Rate Feature
AT*AP0	=Off	The modem does not use the adaptive rate feature.
