AM (Auto-set MY) Command
<Networking and Security> AM Command is used to automatically set the MY (Source Address) parameter from the
factory-set serial number of the modem. The address is formed with bits 29, 28 and 13-0 of the serial number (in that
order). The resulting value is displayed as a result of this command.
AP (API Enable) command
<Serial Interfacing> The AP command is used to enable the modem to operate using the frame-based API operation.
AT (Guard Time After) command
<Command Mode Options> AT Command is used to set/read the time-of-silence that follows the command sequence
character (CC Command) of the AT Command Mode Sequence (BT + CC + AT). By default, 1 second must elapse before
and after the command sequence character.
The times-of-silence surrounding the command sequence character are used to prevent inadvertent entrance into AT
Command Mode.
