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:
Example:
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 19.3, Available AT Commands and Dependency on SIM
PIN uses the same symbols.
ASC0: Is the AT command supported on the physical serial interface ASC0?
+ Yes
- No
Note: In the case of BGS2T only "Yes" applies.
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: Columns MUX1, MUX2 and MUX3 are relevant only if the GSM Mobile Engine operates in Mul-
tiplex mode, that is, if the physical serial interface is partitioned into 3 virtual channels by using
the Multiplexer protocol. Command usage is the same on ASC0 and MUX1.
Is the AT command supported in ALARM 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.
