the ranges are from 0 to 31, from 0 to 63, from 0 to 127 and from 0 to 255
respectively.
--press Stop Bit to select "1 bit" or "2 bit".
--press Even-Odd to select "None", "Odd" or "Even".
Baud Rate:
Set the baud rate of data transmission (equal to specifying a clock frequency). Press
Baud to set the desired baud rate to 2400 bps, 4800 bps, 9600 bps (default), 19200
bps, 38400 bps, 57600 bps, 115200 bps, 230400 bps, 460800 bps, 921600 bps, 1
Mbps or User. When "User" is selected, press Setup and use
the navigation knob to adjust the baud rate at a relatively smaller step or turn the
