How Does The NDIS PIM 9X Driver Work With The Dial-Up Adapter?
As many developers have found out, the Dial-Up Adapter makes some proprietary checks, and only allows the MSTCP protocol to acquire a completely functional binding using the normal NDIS binding methods. These checks don’t matter to the NDIS PIM 9X driver because it has access to the NDIS handles created by MSTCP itself. This makes packet filtering of sends and receives on the Dial-Up adapter possible.
