As shown in
received byte back to the PTB1/TXD pin for error checking.
Any result of a command appears after the echo of the last byte of the
command.
A start bit, followed by nine low bits, is a break signal. See
When the monitor receives a break signal, it delays two bit times before
echoing the break signal.
