Re: help with port sensing program
This is how you know what device to write to....
Every NIC card on your system has a unique identifier in the registry.
Go to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards.
Then there will be subkeys for each card. For instance if there is subkey 2, go to it and you will find a description and ServiceName.
The ServiceName allows you to access the device.
