at the beginning of each command line.
All these AT commands can be split into three categories syntactically: "basic", "S parameter", and
"extended". These are as follows:
1.4.1 Basic syntax
These AT commands have the format of "AT<x><n>", or "AT&<x><n>", where "<x>"is the Command, and
"<n>"is/are the argument(s) for that Command. An example of this is "ATE<n>", which tells the DCE
whether received characters should be echoed back to the DTE according to the value of "<n>". "<n>" is
optional and a default will be used if missing.
1.4.2 S Parameter syntax
These AT commands have the format of "ATS<n>=<m>", where "<n>" is the index of the S register to set,
and "<m>"is the value to assign to it. "<m>" is optional; if it is missing, then a default value is assigned.
1.4.3 Extended Syntax
These commands can operate in several modes, as in the following table:
Table 1: Types of AT commands and responses
Test Command AT+<x>=? The mobile equipment returns the list of parameters and
value ranges set with the corresponding Write Command
or by internal processes.
Read Command AT+<x>? This command retur
ns the currently set value of the
parameter or parameters.
Write Command AT+<x>=<…> This command sets the user-definable parameter values.
Execution Command AT+<x> The execution command reads non-
variable parameters
affected by internal processes in the GSM engine.
1.4.4 Combining AT commands on the same Command line
You can enter several AT commands on the same line. In this case, you do not need to type the "AT" or "at"
prefix before every command. Instead, you only need type "AT" or "at" the beginning of the command line.
Please note to use a semicolon as the command delimiter after an extended command; in basic syntax or S
parameter syntax, the semicolon need not enter, for example: ATE1Q0S0=1V1X4;+IPR=115200;
The Command line buffer can accept a maximum of 1024 characters (counted from the first command
without “AT” or “at” prefix). If the characters entered exceeded this number then none of the Command
will executed and TA will return "ERROR".
1.4.5 Entering successive AT commands on separate lines
