WAN-Specific Capabilities of CoNDIS WAN Drivers (NDIS 5.1)
Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.
CoNDIS WAN drivers differ from a non-WAN CoNDIS drivers as follows:
CoNDIS WAN drivers that support TAPI services use the CO_ADDRESS_FAMILY_TAPI_PROXY address family.
CoNDIS WAN drivers support WAN-specific OIDs: OID_WAN_PERMANENT_ADDRESS, OID_WAN_CURRENT_ADDRESS, and OID_WAN_MEDIUM_SUBTYPE.
CoNDIS WAN miniport drivers support a set of CoNDIS WAN OIDs to set and query operating characteristics. For more information about CoNDIS WAN OIDs, see CoNDIS WAN Objects.
CoNDIS WAN miniport drivers that provide TAPI services support a set of CoNDIS TAPI OIDs to set and query operating characteristics. For more information about CoNDIS TAPI OIDs, see TAPI Extensions for Connection-Oriented NDIS.
CoNDIS WAN miniport drivers support a set of WAN-specific status indications that denote changes in the status of a link. For more information about CoNDIS WAN miniport driver status indications, see Indicating CoNDIS WAN Miniport Driver Status.
CoNDIS WAN miniport drivers keep a WAN-specific set of statistics. The OID_WAN_CO_GET_STATS_INFO OID requests the miniport driver to return the statistics information.
CoNDIS WAN miniport drivers never attempt to loop back any packets; NDISWAN provides loop-back support.
