Chapter 4 - Command Mode
Number Linking NN
You may command the modem to dial another number automatically if the first number dialed is
busy. This would be useful in a situation where a computer can be accessed through more than one
phone number. This is called
“linking”.
To link the number in N1 to the number N2, simply enter ATN1N2 and hit RETURN. Several numbers
can be linked in the same command. For example, you could link N1 to N2 to N3 to N4 by entering
ATN1N2N3N4 and RETURN or you could link N1 to N2 and back to N1 and then back to N2 by
entering ATN1N2N1N2 and RETURN.
The only limit on the number of numbers that can be linked is the 60 characters allowed in a
command line. Number linking can not be used with blind dialing, since busy signals would not be
detected. You would have to select the Wait-for-Dial tone dialing method using the
X Command in
order to use the Number Linking feature.
Listing Numbers Stored in Memory L
Telephone numbers that you have stored in the modem’s memory may be listed and displayed with
the L command. It will display all ten stored N numbers in a format like that shown below. All digits
and command letters will be shown. The number’s
“name” (0 thru 9) is shown first, followed by the
complete dialing command and telephone number as originally entered.
Simply enter ATL and hit RETURN to display these numbers on your video screen or printer. An
example of an L command listing is shown below:

4.4.4 Configuration and Default Storage Commands
Store Configuration & S-Register Parameters in Non-Volatile Memory &W
The modem can store configuration parameters and S-Register values in its nonvolatile read/write
Random Access Memory (RAM) memory. The &W command does this, which prevents any re-
configuration from being lost on a power-down or Reset (
ATZ) condition.
&W0 (or AT&W) causes the modem to store your customized AT command settings and S-Register
values in its nonvolatile RAM.
&W0 also sets the modem so that it reads your customized settings
stored in nonvolatile RAM when powered down or reset. (The &W0 command only changes the
settings stored in nonvolatile RAM that you specifically intend to alter. All other default parameters
are applicable.)
&W1 causes the modem not to store your customized settings to nonvolatile RAM so that, after
powering down or resetting the modem, it reads the factory default settings stored in ROM.
