Phone Number Memory Commands
ISIHP modems can store up to four telephone numbers in nonvolatile
memory. You can store the numbers with the &Z command and dial them
with the ATDS command.
&Zn=s Store a Phone Number
s = phone number
n= 0, 1, 2 or 3
Default: none
You can store a telephone number string in the modems phone number
memory. You can store four of these strings using the &Zn=s command.
The memory locations are labeled N0 through N3. For example, the
telephone number 1-612-555-1212 is stored at memory location N2 by
typing &Z2=16125551212 and pressing ENTER.
DSn Dial a Stored Number
n = 0, 1, 2, or 3
Default: none
You can automatically dial a telephone number that is stored in the modems
number memory by typing ATDSn, where n = 0 through 3. For example,
you can dial a number stored at N2 by typing ATDS2 in terminal mode and
pressing ENTER.
Configuration Storage and Recall Commands
The ISIHP-2S/2U 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 cannot change the
default parameters in ROM, but 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.
