Chapter 5 - AT Commands
S32 Escape Sequence Timeout
Unit: 100 ms
Range: 0–255
Default: 20
Sets the time allowed in an escape sequence from the receipt of the A in AT to the receipt of
the carriage return. If the S32 time interval expires before you press ENTER, the escape
sequence ends. The default time is 2 seconds.
S34 Maximum Escape Sequence Length
Unit: Decimal ASCII code
Range: 0–10
Default: 2
Sets the maximum character length of the escape sequence, not including +++AT. For
example, a character length of S34=2 allows two characters after +++AT (e.g., +++ATH0).
Conversely, an invalid escape sequence (too many characters placed in the command string)
passes through as data (e.g., +++atili2). The maximum length of the escape sequence is 10
characters.
S50 Caller Line ID CLI
Unit: Decimal ASCII code
Range: 0 or 1
Default: 0 (disable CLI)
Sets whether the mechanism for identifying the two endpoints of a connection is enabled or
disabled. Since RING messages only appear for ISDN data calls, the CLI feature does not
define a means of conveying Calling Party information to the terminal for ISDN voice calls.
The CLI information is only included with the first RING message for a given incoming call,
and appears as follows:
RING FM: 5552000 TO: 5551000
If the Calling Party Number information is not included in the incoming SETUP message, the
RING message appears as follows:
RING TO: 5551000
If the Called Party Number information is not included in the incoming SETUP message, the
RING message will appear as follows:
RING FM: 5552000
If neither the Called Party Number nor the Calling Party Number is included in the incoming
SETUP message, the RING message will contain no additional information.
S52 Auto-Protocol Detection
Usage: S52=n; S52?
Function: Auto-Protocol Detection
Unit: Decimal ASCII code
Range: n=0—Disable,
n=1—Detect,
n=2—Detect and Select
Default: 1 (Detect)
Enables or disables the ability to identify the reception of V.120, X.75, or PPP data calls. The
