The maximum data length of a Modbus transmission is 256 bytes. This results in
a user data length of 253 bytes.
The number of data bits and stop bits is defined in the Modbus definition. Baud
rates of less than 4800 baud are possible by definition, but not implemented at
present. The interface parameters can only be configured on the device (not via
bus).

Device settings
The settings are read with the 0x04 command (read input registers) in accordance with
table 1. Writing is not possible at present.
