want to reconfigure or read the contents of an S-Register. This section describes how to read and
change S-Register values.
This section is in two parts:
•
The first part describes the AT commands used to display and change S-Register values.
•
The second part describes S-Registers used by the modem.
Any S-Register that is not stored in memory is reset to its default value when you:
•
Power up the modem
•
Load a new Option Set
•
Reinitialize memory
Displaying and Changing S-Register Values
This command displays the value of S-Register
n
, as stored in volatile memory.
If a “?” appears in the command string anywhere other than immediately following the S-Register
number, the command displays the value of the last S-Register selected.
If you try to read the value of an unused S-Register, the modem displays
OK
.
Display S-Register Value (AT?)
This command displays the contents of the “selected” S-Register, as stored in volatile memory. The
“selected” S-Register is the last S-Register that was accessed using an S-Register command or the
ATSn command. The number must be within the S-Register’s specified range. On power-up, S-
Register 0 is “selected.”
If you try to read the contents of an unused S-Register, the modem displays
OK
.
Change S-Register Value (ATSx=n)
