Okay.
Is she's used in ATM framing too, or it's just for Ethernet framing?
Just to understand.

(see rfc2684)
Okay, it was near what I'd managed to understand so far.
Thanks for clearing this.

You're great! A nice drawing, it's even better that what I was hoping!
Okay, so where I can find related code of the two top layer?
On LinuxATM web site, and PPPoA patches to pppd, I guess?
On BeOS, there's a existing PPP stack, so I'll be able to get from her /
send to her *plain* PPP frames.

read/write calls of my own BeOS speedtouch.c?
And, more important, is it the more complex two layers?
Because in this case I think I'll look for some help from far more ATM-aware
brain than mine.

Okay, great news.

Thanks you very much for your great reply, it's far more clear in my mind
now.
