NM uses a new device NMDeviceModem to dial out (in process) and starts pppd process. The dbus interface will remain the same as for all the other devices, just the activation structure will contain modem and ppp specific data. If we want (and probably do), we can add a new dbus interface for dialup devices (just like wired and wireless devices have their own device specific interface in addition to the standard device interface) that has additional status signals for better progress reporting (like, "initializing modem", "dialing", ...). pppd process will emit dbus signals (with help from a pppd plugin) so NM knows what's going on. > > That is yet not all, it also turns out HAL doesn't have any notion of > > modems so the best we can do for now is to get a list of HAL devices > > with capability "serial" and try to send some modem initialization > > strings and see if they respond.

Somehow we'll gotta figure which is which. :) Yeah, this is unfortunate. Pretty much identical to the wireless situation until wpa_supplicant provided us with a standard interface. I guess for each of these multi-device card we'll have to write a NMDeviceModem subclass, ugh.
