it is more like this:
modem -> TTY -> PPP -> TUN/TAP -> Kernel Net-Stack -> socket -> application.
With the TTY being in kernel, the PPP being in userspace, and TUN/TAP
etc. begin in the kernel again.
A future enhancement is to use the kernel PPP layer, but we haven't
gotten there yet.
Regards
Marcel
