for adsl we must write wan miniport driver ? or miniport driver with wdm
lower interface ? or other ?
thanks
Low-end ADSL hardware exposes itself as an Ethernet to the OS. The OS then
runs PPPoE over it. So, you need to write a usual NDIS miniport. As about WDM
lower egde - it depends on how the hardware is connected to the computer. If
this is USB - then yes, you need an NDIS/WDM miniport with lower egde talking
to USB.
In Windows, “WAN” means “PPP”, and PPP appears on a layer above the ADSL
hardware. ADSL uses the ATM-format packets on some low level, and then runs
Ethernet on top of it (which is RFC 1483 IIRC). Then PPPoE is runned over this
Ethernet, and IP is runned over this PPP link, so that the provider can check
the password and billing and lease an IP address.
High-end ADSL hardware is a full-blown router, which requires no Windows
software installed.
