Read returns zero.
Deglitch Sample Rate.
Sets the sample rate for the deglitch algorithm and the off-hook intrusion algorithm
(40 ms units).
0000000 = Disables the deglitch algorithm, and sets the off-hook intrusion sample rate to
200 ms and delay between compared samples to 800 ms.
Read returns zero.
Invert CTS pin.
0 = Inverted (CTS).
1 = Normal (CTS).
Read returns zero.
0 = 8N1.
1 = 9N1 (hardware UART only).
