Sending and Receiving Data (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 x has been deprecated and is superseded by NDIS 6.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.
Transferring data involves sending or receiving packets over an established and activated VC.
Note Protocol drivers must not call NdisCoSendPackets to send data to a VC after calling NdisClCloseCall for that VC.
