Hello,

We need a ppp interface for our modem. I was told on the chat forum that =

a tap/tun device was to be used. Has anyone else started with this or =

thought how to implement this?

After reading briefly the code from pppd, the implementation, for a =

first draft, is pretty straight forward (w/o encryption, etc. in =

userspace). "Just" dial the apn, and hand over the tty fd to ppp via ioctl.

Steps (borrowed from pppd):

1. Dial the apn (in ofonod).
2. Some synchronization code.
3. hand over tty fd to ppp driver via ioctl. the IP.

I know i am simplifying the process.

Is this the way to go?


Regards,
Ryan
