U-90E Data/Fax Modem 4.4 Non-Volatile Memory The U-90E has an amount of memory set aside for storing user information such as frequently used phone numbers and default command settings. The latter is particularly useful when using your modem to call a variety of different locations that require different settings. For this reason, your modem provides a number of user "Profiles" that can be accessed through simple AT commands. This section gives information about storing phone numbers, and saving default settings in the power-on profile. 4.4.1 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 49 that represents the location in memory where the phone number can 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 You can store up to 50 telephone numbers. 4.4.2 Dialing Stored Phone Numbers The AT command syntax used to dial a stored number is ATDS=n. The 'n' is the memory location of the stored number you want to dial. NOTE: As a general rule, when a letter in an AT command definition is shown in italic type, the letter is not to be entered as part of the command, but rather is representative of a number or string expected as input. For example: The letter 'S' in the ATDS=n command is actually typed, unlike the 's' in the AT&Zs=n command which represents a number. 4-8 Basic Modem Operation

U-90E Data/Fax Modem
4.4
Non-Volatile Memory
The U-90E has an amount of memory set aside for storing user information such as frequently used
phone numbers and default command settings. The latter is particularly useful when using your
modem to call a variety of different locations that require different settings. For this reason, your
modem provides a number of user “Profiles” that can be accessed through simple
AT
commands.
This section gives information about storing phone numbers, and saving default settings in the
power-on profile.
4.4.1 Storing Phone Numbers
The
AT
command to store a phone number is in the format
AT&Z
s
=
n
.
The ‘
s
’ is a number from 0 to 49 that represents the location in memory where the phone number
can 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 50 telephone numbers.
4.4.2 Dialing Stored Phone Numbers
The
AT
command syntax used to dial a stored number is
ATDS=
n
.
The ‘
n
’ is the memory location of the stored number you want to dial.
NOTE:
As a general rule, when a letter in an
AT
command definition is shown in italic type, the
letter is not to be entered as part of the command, but rather is representative of a number or string
expected as input. For example: The letter ‘S’ in the
ATDS=
n
command is actually typed, unlike
the ‘
s
’ in the
AT&Z
s
=
n
command which represents a number.
