communication port will accept Modbus RTU frames only. To make this port go back

C.5: Error Reply
In the case of an unsupported function, or any other recognizable error, an error reply
will be generated from the Shark® 200 meter to the Primary station (the requester).
The Internal Indicator field will report the type of error: unsupported function or bad
parameter.
The broadcast acknowledge and restart bit, are also signaled in the internal indicator
but they do not indicate an error condition.
