Operating Mode S70
The S70 register determines the protocol operating mode and action
taken on an MNP link attempt failure. LAPM is assigned highest
priority.
Example: With \N7 selected the modem tries a LAPM connection first;
if unsuccessful the modem tries an MNP connection; if also unsuc-
cessful the modem connects in normal mode. Modes allowing protocol
fallback are referred to as auto-reliable.
