Chapter 3 - Basic Modem Operation
3-6
For example, to read the value of S-register S35, bit 7, type ATS35.7? and press
Enter. The modem responds with an appropriate value, followed by OK.
Changing S Register Values
You can use the ATS0=n command to change the value of an S-register.
For example, to have your modem auto-answer an incoming call after two rings,
set S-register 0 to 2. Be sure the n value is between 1 and 255. If n is set to 0,
your modem will not answer incoming calls.
Non-Volatile Memory
The Omni 288S has an amount of memory set aside for storing user information
such as frequently used phone numbers and default command settings. This latter
is particularly useful when you use your modem to call a variety of different
locations that require different settings. For this reason, the Omni 288S provides a
number of user “Profiles” 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 49 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 50 telephone numbers.
Dialing Stored Phone Numbers
The AT command syntax used to dial a store 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.
