Communication via Modbus requires the interaction between a single Modbus client instance and multiple Modbus server. This class provides the Modbus server implementation via a serial port.
Since multiple Modbus server instances can interact with a Modbus client at the same time (using a serial bus), servers are identified by their

- Return type:
Returns the amount of microseconds for the silent interval between two consecutive Modbus messages.
microseconds – int
Sets the amount of
microseconds for the silent interval between two consecutive Modbus messages. By default, the class implementation will use a pre-calculated value according to the Modbus specification. A active or running connection is not affected by such delay changes.
microseconds is set to -1 or
microseconds is less than the pre-calculated delay then this pre-calculated value is used as frame delay.
