[Winpcap-users] Regarding sniffing on multiple interfaces.

[Helmut Vaupotitsch]

My solution is to check periodically if a physical link is active via 
PacketRequest (OID_GEN_MEDIA_CONNECT_STATUS)

I know this way is not recommended(calling packet.dll directly), but i 
found no better/handsome solution.

Regards from Austria
Helmut
