BX

ES:DI
Number of available received packets
Number of sent packets completed (provisional)
Device handle from the IfaceHandle member of the DevUserDriver structure used at the
DEV_OPEN_IFACE call.
Return Value
Comments
DX = 0, AX = 0
This function should only be called from the device driver specific ISR. It can be used to signal a receiver task
which is waiting at the DEV_RECV_WAIT call. In this case the number of received packets should be set in
BX register.
The current implementation does not support a transmit task. The sent packets count in CX is a provision for
informing a transmit task about completion of packet transmission.
For more detailed description see How to add a user device driver/link layer interface.
CLIB TCPIP.C implementation of this function:
int Dev_Notify_ISR( DevUserIfaceHandle DevHandlePtr,
unsigned int rcvdPackets,
unsigned int sentPackets);
