<html><body><div style="color:#000; background-color:#fff; font-family:Courier New, courier, monaco, monospace, sans-serif;font-size:14pt"><div class="" style="">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!</div><div class="" style=""> </div></div></body></html>
