Implementation

@override
Future<ProtocolDataUnit> send(int slaveId, ProtocolDataUnit request) async {
  final aduRequest = _encodeASCIIFrame(slaveId, request);
  final aduResponse = await sendRawFrame(aduRequest);
  final (rspSlaveId, pdu) = _decodeASCIIFrame(aduResponse);
  final response = ProtocolDataUnit(pdu[0], pdu.sublist(1));

  _verify(slaveId, rspSlaveId, request, response);
  return response;
}
