Use this data item to select the maximum configured baud rate for all
devices connected to the UART port. Refer to your users manual for
details on why this baud rate needs to be selected. Setting a value of
176 selects a max baud rate of 19.2 kbaud. Setting a value to this
item at 48 selects a max baud rate of 38.4 kbaud. Values other than
176 or 48 are ignored.
