Async
This protocol uses asynchronous data transmission that sends an 8-bit byte with 1 start bit, 8 data bits and 1 stop bit. The minimum signal is four bytes. The protocol is reported as Asyncn:min-max:aa.bb...yy.zz where n is the number of bytes, min-max is the range of durations in microseconds that was taken as a single bit and aa.bb...yy.zz are the first two and last two byte values in hexadecimal notation.
