that can be accessed through simple AT commands. This section covers the topics of
storing phone numbers, and saving default settings in the power-on profile.
Storing Phone Numbers
The AT command to store a phone number is in the format AT&Zs=n.
The ‘s’ is a number from 0 to 3 that represents the location in memory that the phone
number is to be stored, and the ‘n’ is the phone number itself.
Example: To store the number ‘1-714-555-1212’ in memory location ‘2’, type:
AT&Z2=17145551212<Enter>
You can store up to 4 telephone numbers.
Dialing Stored Phone Numbers
The AT command syntax used to dial a store number is ATDSn.
The ‘n’ is the memory location of the stored number you want to dial.

Saving Settings and User Profiles
There are some cases where you may wish to save the settings you have made as the
default settings that are recalled when the Comet 336 is powered up. The AT&WZ
command selects the current settings as the power-on profile.
There are four profiles that can be changed by the user, and one factory default profile.
The following table lists the syntax for the command involved in storing, recalling, and
viewing the profile settings.
AT&Vn Views the settings in profile (n-1); n=0 to 2; n=0 views current settings;
n=3 views factory settings
AT&Wn Stores the current settings in user profile ‘n’; n=0 to 1
ATZn Resets the current settings with the settings in profile ‘n’, n=0 to 1
Resets the current settings with the factory settings, n=2
Helpful Hints for PC Computers
Usually, serial ports are manufactured in two forms, either with a 25 or 9-pin male jack.
For high speed serial connections at 230.4Kbps or 460.8Kbps, use a low-capacitance
cable. Also, keep the cable as short as possible.
