[Winpcap-users] how to detect an idle adapter?

I have two adapters, one is connected to network and the other is idled (adapter itself enabled but no RJ45 cable connected). How can I detect this idle one? Calling pcap_sendpacket() returns successfully even for this idle adapter - this looks like a bug for me. This idle adapter has kept IP address from its last use when connected to network so I can't check if its IP address equals to null to determine. Any hints? Thanks!
