That seems really strange.  What atm network interface are you using?
I am guess it is some usb atm device?

I don't think pppoatm will send packets if it doesn't know what
encapsulation is being used, so even if pppd sends packets to the
pppoatm layer, pppoatm is not going to send them.  The pppoatm module
attempts to learn the encapsulation by looking at the arriving pdu's.

I forgot.  This doesn't report AAL5 statistics but rather shows that
the pvc is open and the traffic classes assigned.  However, atmdiag (if
things are functioning) should be reporting total sent and received
PDU's.
