This object identifier requests information about whether the media is busy — that is, whether the miniport driver detects packet traffic.
For a set, the miniport driver can start to monitor the media for a busy condition. IrLAP sets the value of OID_IRDA_MEDIA_BUSY to 0 to inform the miniport driver to monitor for a media-busy condition. If the miniport driver detects infrared traffic of any kind, it must:
- Set the value of OID_IRDA_MEDIA_BUSY to nonzero.
- Call the NdisMIndicateStatus function to indicate that the media is busy. In this call, the miniport driver passes NDIS_STATUS_MEDIA_BUSY in the GeneralStatus parameter.
After the value of OID_IRDA_MEDIA_BUSY is set to nonzero, the miniport driver does not monitor the media for a busy condition again until IrLAP resets OID_IRDA_MEDIA_BUSY to 0.
For a query, the miniport driver determines if media is currently busy. The miniport driver returns a 0 value if the media is not busy. The miniport driver returns a nonzero value if it detects packet traffic.
