The main characteristic of this mode is that the RF is switched off and therefore only a limited
set of AT commands is available. The mode can be entered or left using the appropriate
at^scfg command. This AT command can also be used to configure the airplane mode as the
standard startup mode, see . The JVM is started when autostart is enabled. A Java
application must be able to handle this mode. The airplane mode is indicated by URC
"SYSSTART AIRPLANE MODE". Since the radio is off all classes related to networking
connections, e.g. SocketConnection, UDPDatagramConnection, SocketServerConnection,
HTTPConnection, will through an exception when accessed.
The ALARM can be set by the at+cala AT command. Please refer to the AT Command Set
 and Hardware Interface Description  for more information. One can set an alarm, switch
off the module with at^smso, and have the module restart at the time set with at+cala. When
the alarm triggers the module restarts in a limited functionality mode, the "airplane mode".
Only a limited number of AT commands is available in this mode, though the JVM is started
when autostart is enabled. A Java application must be able to handle this mode and reset the
module to reinstate the normal mode.
The airplane mode is indicated by URC "SYSSTART AIRPLANE MODE".
Note: For detailed information which functionality is available in this mode see . The mode
indicating URC is created after issuing the very first AT command on any opened channel.
