busybox has pppd? hrmm I think not. But this might possibly be useful.
pppd is pretty big. But then again it would be a lot of work since the
kernel ppp interface changes more often than nfs, and busybox mount has a
hard time keeping up with that.

pppd will work on any character device. You can make it use the console.
The kernel makes the translation from character device to hardware. You
might be better off writing your own driver though. PPP isn't designed for
super high speed connections (like a pci bus :), but I suppose it might
work for your purposes.
