  81  * The way this plugin works is following:
  82  *
  83  *   powered -> SubscriberIdentity or Online = True -> gprs, context ->
  84  *     attached -> netreg -> ready
  85  *
  86  * Depending on the modem type, this plugin will behave differently.
  87  *
  88  * GSM working flow:
  89  *
  90  * When a new modem appears, the plugin always powers it up. This
  91  * allows the plugin to create a connman_device. The core will call
  92  * modem_enable() if the technology is enabled. modem_enable() will
  93  * then set the modem online. If the technology is disabled then
  94  * modem_disable() will just set the modem offline. The modem is
  95  * always kept powered all the time.
  96  *
  97  * After setting the modem online the plugin waits for the
  98  * ConnectionManager and ConnectionContext to appear. When the context
  99  * signals that it is attached and the NetworkRegistration interface
 100  * appears, a new Service will be created and registered at the core.
 101  *
 102  * When asked to connect to the network (network_connect()) the plugin
 103  * will set the Active property on the context. If this operation is
 104  * successful the modem is connected to the network. oFono will inform
 105  * the plugin about IP configuration through the updating the context's
 106  * properties.
 107  *
 108  * CDMA working flow:
 109  *
 110  * When a new modem appears, the plugin always powers it up. This
 111  * allows the plugin to create connman_device either using IMSI either
 112  * using modem Serial if the modem got a SIM interface or not.
 113  *
 114  * As for GSM, the core will call modem_enable() if the technology
 115  * is enabled. modem_enable() will then set the modem online.
 116  * If the technology is disabled then modem_disable() will just set the
 117  * modem offline. The modem is always kept powered all the time.
 118  *
 119  * After setting the modem online the plugin waits for CdmaConnectionManager
 120  * interface to appear. Then, once CdmaNetworkRegistration appears, a new
 121  * Service will be created and registered at the core.
 122  *
 123  * When asked to connect to the network (network_connect()) the plugin
 124  * will power up the CdmaConnectionManager interface.
 125  * If the operation is successful the modem is connected to the network.
 126  * oFono will inform the plugin about IP configuration through the
 127  * updating CdmaConnectionManager settings properties.
