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.
