Questions about NDISWan miniport

Hi, All,

I’ve built a NDISWAN Miniport driver and installed into system(W2K). Two
questions came out.

(1)My driver is based on serial port(PCI COMx) instead of ethernet card.
But when I install my driver via “control panel”->“Add/Remove Hardware”,
NDIS send extra two queries about ether netcard info into my driver. They
are OID_802_3_MAXIMUM_LIST_SIZE and OID_802_3_CURRENT_ADDRESS. If I didnot
accept the two queries and send back the dummy values , the driver
installation faild with error code 10. Are there two OID required for the
NDIS WAN iniport driver based on any medium or not? If not, how can I avoid
the NDIS sending these two queries?

(2)Once I install my miniport driver successfully, how can I activate my
driver so that all TCP/IP/PPP outgoing traffic will use my miniport driver
to pass into lower device layer(in my case, serial port)? The StartType for
this driver is service-demand-start.

Thanks in advance,

Regards,

H. H.
