Dear Sir
 
Under windows 98SE or ME, there are some interesting situation at Winpcap 3.0 release version.
 
1. 
If the NIC driver is disabed, the interface handler still can be opened by PacketOpenAdapter(). 
2.
Switch the NIC driver on and off several times, if current NIC is disabled, the function PacketRequest() will be halt.
Because of the error code of return value of DeviceIoControl() is IO_ERROR_PENDING.
 
Does it hardware depend or not? Or something else ?
 
If you have any suggestion or advice, please let me know. Thanks.
 
Regards,
