> 1.3.1 | Quick reference table

> Each AT command description includes a table similar to the example shown below. The table is intended as a quick reference to indicate the following functions:

> PIN: | Is the AT command PIN protected?
> | + | Yes
> | - | No
> | ± | Usage is dependent on conditions specified for the command, or not all command types are PIN protected (for example write command PIN protected, read command not).
> | Note: | The table provided in Section 23.3, Available AT Commands and Dependency on SIM PIN uses the same symbols.

> ASC0: | Is the AT command supported on the first physical serial interface ASC0?
> | + | Yes
> | - | No

> ASC1: | Is the AT command supported on the second physical serial interface ASC1?
> | + | Yes
> | - | No
> USB: | Is the AT command supported on the USB interface?
> | + | Yes
> | - | No

> MUXn: | Is the AT command usable on the Multiplexer channels MUX1, MUX2, MUX3?
> | + | Yes
> | - | No
> | ± | AT command is usable, but under the restrictions specified in the section related to the command.
> | Note: | The columns MUX1, MUX2 and MUX3 are relevant only when the GSM engine operates in Multiplexer mode, that is, when the first physical serial interface is partitioned into 3 virtual channels by using the Multiplexer protocol. Usage is the same on ASC0 and MUX1.
> Q | Is the AT command supported in AIRPLANE mode?
> | + | Yes
> | - | No
> | ± | In AIRPLANE mode, not all described functions are available. For example, the test or read command is usable, the write or execute command is not. Furthermore, only some of the listed parameters can be changed in AIRPLANE mode. A typical example is AT^SCFG that controls different features.
> Charge: | Is the AT command supported in CHARGE ONLY mode?
> | + | Yes
> | - | No
> | ± | AT command is usable, but under the restrictions specified in the section related to the command.
> Last: | If commands are concatenated, this AT command must be the last one.
> | + | Yes
> | - | No
> | Note: | See also Section 1.4, AT Command Syntax for details on concatenated AT commands.

> Example:

> PIN |  | ASC0 | ASC1 | USB | MUX1 | MUX2 | MUX3 |  |  | Charge | Q | Last
> - |  | + | + | + | ± | ± | ± |  |  | + | - | -
