## Description

The Modem interface controls the status and actions in a given modem object.

## Method Details

### The Enable() method

    Enable (IN  b enable);

Enable or disable the modem.

When enabled, the modem's radio is powered on and data sessions, voice calls, location services, and Short Message Service may be available.

When disabled, the modem enters low-power state and no network-related operations are available.

`IN b `enable``: | `TRUE` to enable the modem and `FALSE` to disable it.

### The ListBearers() method

    ListBearers (OUT ao bearers);

List configured packet data bearers (EPS Bearers, PDP Contexts, or CDMA2000 Packet Data Sessions).

`OUT ao `bearers``: | The list of bearer object paths.

### The CreateBearer() method

    CreateBearer (IN  a{sv} properties,
                  OUT o     path);

Create a new packet data bearer using the given characteristics.

This request may fail if the modem does not support additional bearers, if too many bearers are already defined, or if properties are invalid.

Allowed properties are:

`"apn"` | Access Point Name, given as a string value (signature `"s"`). Required in 3GPP.
`"ip-type"` | Addressing type, given as a MMBearerIpFamily value (signature `"u"`). Optional in 3GPP and CDMA.
`"allowed-auth"` | The authentication method to use, given as a MMBearerAllowedAuth value (signature `"u"`). Optional in 3GPP.
`"user"` | User name (if any) required by the network, given as a string value (signature `"s"`). Optional in 3GPP.
`"password"` | Password (if any) required by the network, given as a string value (signature `"s"`). Optional in 3GPP.
`"allow-roaming"` | Flag to tell whether connection is allowed during roaming, given as a boolean value (signature `"b"`). Optional in 3GPP.
`"rm-protocol"` | Protocol of the Rm interface, given as a MMModemCdmaRmProtocol value (signature `"u"`). Optional in CDMA.
`"number"` | Telephone number to dial, given as a string value (signature `"s"`). Required in POTS.

Some properties are only applicable to a bearer of certain access technologies, for example the `"apn"` property is not applicable to CDMA2000 Packet Data Session bearers.

`IN a{sv} `properties``: | List of properties to assign to the bearer after creating it.
`OUT o `path``: | On success, the object path of the newly created bearer.

### The DeleteBearer() method

    DeleteBearer (IN  o bearer);

Delete an existing packet data bearer.

If the bearer is currently active and providing packet data server, it will be disconnected and that packet data service will terminate.

`IN o `bearer``: | Object path of the bearer to delete.

### The Reset() method

    Reset ();

Clear non-persistent configuration and state, and return the device to a newly-powered-on state.

This command may power-cycle the device.

### The FactoryReset() method

    FactoryReset (IN  s code);

Clear the modem's configuration (including persistent configuration and state), and return the device to a factory-default state.

If not required by the modem, `code` may be ignored.

This command may or may not power-cycle the device.

`IN s `code``: | Carrier-supplied code required to reset the modem.

### The SetPowerState() method

    SetPowerState (IN  u state);
