Velocity of data transfer in Bit/s (Baud).
01h: 150 Baud 05h: 1800 Baud 09h: 9600 Baud 0Dh: 57600 Baud
02h: 300 Baud 06h: 2400 Baud 0Ah: 14400 Baud 0Eh: 115200 Baud
03h: 600 Baud 07h: 4800 Baud 0Bh: 19200 Baud

Number of data bits where a character is mapped to.
0: 5Bit 1: 6Bit 2: 7Bit 3: 8Bit
Supported values:
Bit ASCII STX/ETX 3964R USS Modbus RTU Modbus ASCII
5 x x
6 x x x
7 x x x x
8 x x x x x x
The parity is -depending on the value- even or odd. For parity control, the
information bits are extended with the parity bit, that amends via its value
("0" or "1") the value of all bits to a defined status. If no parity is set, the
parity bit is set to "1", but not evaluated.
0: NONE 1: ODD 2: EVEN
The stop bits are set at the end of each transferred character and mark the
end of a character.
1: 1Bit 2: 1.5Bit 3: 2Bit
1.5Bit can only be used with CharLen 5 at this number of data 2Bit is not
allowed.
With this bit you affect the behavior from signal Request to send
"0" = RTS off
"1" = RTS is "0" at Receive
RTS is "1" at Send
Note: For RS485 FlowControl must be "1" !
