AT Command
When using a terminal application, you will need to manually type in each
command.
• For most commands, when you are entering them using a terminal
connection, you will need to preface the command with AT (exceptions are
noted), i.e. ATA which is listed as A.
• Some commands have specific parameters while other commands will take
whatever you type.
• Required variable parameters are denoted with italicized text, example, Dn.
The n is variable.
• Acceptable parameters and/or specific formats are listed with each
command.
• Most commands with parameters can be entered with ? to read the current
value (for example, AT& D ? will respond with “2” if the default has not been
changed).
• Optional parameters are denoted with square brackets [ ].
