6 Status Registers Operating Mode S70 The S70 register determines the protocol operating mode and action taken on an error correcting 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 unsuccessful the modem connects in normal mode. Modes allowing protocol fallback are referred to as auto-reliable.
