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
