Question; read_holding-registers()

[Vic Schme]

Is there a method available to read non-contiguous set of registers from a modbus slave?

Thanks,

Victor

You should be able to use the same `read_holding_registers` or `read_input_registers` to get the registers. The response depends on slave and how it handles non contiguous registers.
