2. Enable Sync Baudrate(RF2217 Similar) function when needed; send RFC2217 data package from the
network side to N580 to change the corresponding serial parameters.
3. Test example:
Protocol command:
55AA5501C2008346 set the serial parameters to 115200,N, 8, 1
55AA550025808328 set the serial parameters to 9600, N, 8, 1
