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 modem’s 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 modem’s 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.
