RS485 io module - KC868-HAv2 released

[yawniek]

is it possible to set line speed for modbus and would you consider open sourcing the modbus firmware so it can be extended?

also it would be useful to have a more clear modbus documentation of the standard modbus functionality.
i got it to work but its unclear which other registers i can write and in general what registers use which value

i am considering this in a bigger installation.
