def Uno_OWSniffer.sniff_115200

(

)

Sniffer always @115200.

Not according to official Standards/Specs but possible to implement
RESET and PRESENCE, READ and WRITE: 115200 Baud, 8 bits, no parity, 1 stop

(no switching of baud rates needed, thus we can control
the possition in the input buffer and it's not lossy)

def Uno_OWSniffer.sniff_TUT214

(

)

Sniffer according to official Standards/Specs.

TUTORIAL 214: Using a UART to Implement a 1-Wire Bus Master
RESET and PRESENCE: 9600 Baud, 8 bits, no parity, 1 stop
READ and WRITE: 115200 Baud, 8 bits, no parity, 1 stop

(fast switching of baud rates is possible, but we cannot
control the possition in the input buffer, thus it's lossy)
