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.
