* once in configure mode, the UART parameter change to 9600bps,n,8,1, and a 'U' ascii character is send out to
ensure the control MCU that in the configure mode. If the 24byte command has effect ，a 'K' ascii character is send
back to control MCU. If configure command format error, an 'E' character will be send back to control MCU. If the
error is the checksum not match , the 1byte right checksum will be send back to control MCU also.
