1 = Pin 3 functions as RI. RI asserts during a ring and negates when no
INT Polarity.
Specifies the polarity of the INT function on pin 11.
0 = An interrupt forces pin 11 low.
1 = An interrupt forces pin 11 high.
Ringback Tone Selector.
Controls the unit step size for registers S19, S1A and S1B.
0 = 53.33 ms units. Necessary for detecting a ringback tone.
1 = 10 ms units. Necessary for detecting a reorder tone.
Enable Hangup on Reorder.
Modem is placed on-hook if a ringback or reorder tone is detected. See S0D[4].
0 = Disable.
1 = Enable.
Enable Hangup on Busy.
Modem is placed on-hook if a busy signal is detected.
0 = Disable.
1 = Enable.
Enable Hangup on Intrusion.
Modem is placed on-hook if parallel intrusion is detected.
0 = Disable.
1 = Enable.
Enable Hangup on Escape.
Modem is placed on-hook if a ESC signal is detected.
0 = Disable.
1 = Enable.
Read returns zero.
