Reply To: NDIS IM driver for analog modem???!!! October 1, 2004 at 1:44 pm #5661 TarasParticipant Why do thing your IM driver will not handle traffic from modems? Look at QoS driver. It is IM mininport but it filters modem`s traffic 🙂 All modem are represented as one NIC with several MAC address, so you can deal with them.
