MT3334HD8 User Guide
20 CommPlete Communications Server
You can automatically dial a telephone number that is stored in the modem’s number memory by typing
ATN
n , where n = 0 or 1. For example, you can dial a number stored at N0 by typing ATN0 in terminal
mode and pressing E NTER .
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.
L List Stored Telephone Numbers
Use the L command to display dialing commands stored in the modem’s nonvolatile memory. Typing
ATL<CR>
displays the stored N numbers in the following format:
0 T14082345678
1 P9,T14089876543
All digits and command letters are displayed. The N number is shown first, followed by the complete
dialing command and telephone number as originally entered.
Configuration Storage and Recall Commands
The MT3334HD8 stores parameters in two places. It stores factory default parameters in read-only
memory (ROM), and customized parameters in nonvolatile random access memory (NVRAM). You can-
not change the default parameters in ROM; however, you can change parameters in temporary memory
and then store them in NVRAM as custom settings. You can then recall the custom settings as if they were
factory default settings.
&Wn Store Configuration
n = 0 or 1
Default: &W1
The &W command stores current AT commands and S-register values in nonvolatile memory, so you
won’t lose your custom settings when you turn off the modem or reset it.
&W0 (or &W) stores all current AT command and S-register values in nonvolatile random access memory
(NVRAM) and configures the modem so that it reads your custom settings in NVRAM when the modem is
turned on or when it is reset with the Z command. (The &F reset command will continue to read the
factory default settings in ROM unless you store the &F9 command.)
&W1 erases your custom settings in NVRAM when the modem is turned off or reset, causing the modem to
read the factory default settings in ROM when it is subsequently turned on or reset.
For further information on how the &W command interacts with the reset commands, see Table 2.
