3.4Phone Number Memory Commands

The modem can store up to two telephone numbers in nonvolatile memory. You can store the numbers with the DsNd command, dial them with the Nd command, link them so that one will be automatically dialed after the other with the NdNe command, or list them with the L command.

DsNd	Store a Phone Number
	s = phone number
	d = 0 or 1
	Default: none
	You can store a telephone number command string of up to 60 characters in the modem’s
	phone number memory. You can store two of these 60-character strings using the DsNd
	command. The memory locations are labeled N0 and N1.
	Store a command line by typing it as you would any other command, appending the
	appropriate Nd memory location.
	For example, the tone-dialed number 1-612-555-1212 is stored at memory location N0 by
	typing ATDT16125551212N0 and pressing ENTER. The number is not dialed with this
	store command.
	After storing a number, check to see that it has been stored correctly by typing ATL and
	pressing ENTER.
	When you store a phone number, you store the entire command string, so you can
	effectively create a macro for each number. For example, if you know a particular number
	needs to have extended result codes, detect busy or dial tone, error correction, XON/XOFF
	flow control, pacing, and data compression enabled, the command to store the entire
	command string at location N0 is ATX4&E1&E5&E13&E15DT16125551212N0.
Nd	Dial a Stored Number
	d = 0 or 1
	Default: none
	You can automatically dial a telephone number that is stored in the modem’s number
	memory by typing ATNn, where n = 0 or 1. For example, you can dial a number stored at N0
	by typing ATN0 in terminal mode and pressing ENTER.

Warning: Do not include the letter D in this command, or the stored number will be erased.

NdNe	Number Linking
	d = 0 or 1
	e = 1 or 0
	Default: none
	Number linking allows the modem to dial a second stored number if the first stored number
	is busy. (See the DsNd command.) This command is useful when a computer can be
	accessed through more than one phone number. However, it cannot be used with blind
	dialing, since busy signals would not be detected.
	To link the number in memory location N0 to the number in N1, type ATN0N1 and press
	ENTER. You can cycle back and forth between two numbers by linking them several times
	in one command: ATN0N1N0N1N0N1<CR>. The only limit on the number of times the
	modem can cycle between two numbers is the 60-character maximum allowed in a
	command line.
