OID_WWAN_PCO
OID_WWAN_PCO reports the status and the payload of a Protocol Configuration Option (PCO) value that the modem has received from a mobile operator network. The PCO value that is returned from the modem corresponds to the PDN that the port number specifies in the OID request structure.
For query requests, the modem first responds with NDIS_STATUS_INDICATION_REQUIRED when it receives this OID. An NDIS_STATUS_WWAN_PCO_STATUS notification will be returned containing an NDIS_WWAN_PCO_STATUS structure when the query request is completed. NDIS_WWAN_PCO_STATUS, in turn, contains the PCO status and a WWAN_PCO_VALUE structure that represents the PCO value.
Set requests are not applicable.
Remarks
For modems that choose to use the Microsoft inbox miniport class driver, to receive query requests from the host, the modem must advertise that it supports the new MBIM_CID_PCO CID (index = 9) in the MBB_UUID_BASIC_CONNECT_EXT_CONSTANT service when responding to an MBIM_CID_DEVICE_SERVICES query. For more info about MBIM_CID_PCO, see MB Protocol Configuration Options (PCO) operations.
For modems that choose not use Microsoft inbox miniport class driver, to receive query requests from WWANSVC, the modem’s miniport driver must advertise that it supports the WWAN_OPTIONAL_SERVICE_CAPS_PCO option when responding to OID OID_WWAN_DEVICE_CAPS_EX query requests.
