AFAIK that's the PPP negotiation. If you manually open a connection to any PPP wserver with minicom or equiv. that stuff comes back. Usually the modem returns CONNECT first, and the device is handed over to the PPP code so this doesn't get traced, but here CONNECT comes later, and then we see that PPP is correctly detected:

Correct, that is the ppp negotiation
