Baud rate: Works setting = 4800 Baud.
The baud rate can be set with the first three switches. The transmission
rates of 4800 to 230 400 baud are sustained.
Parity: Works setting = no parity
This switch activates transmission with parity bit.
Even nOdd: Works setting = Odd
With activated parity bit it is possible to switch between Even and Odd
parity.
2 Stopp-Bit: Works setting = 1 Stopp Bit
This switch allows an additional Stopp Bit to be sent.
Long Break: Works setting = no extension
This switch allows the delay time between master inquiry and slave reply to
be increased by 3.5 bytes.
