      Description

      I'm using convertor Moxa NPort that creates a virtual COM port instead Modbus TCP but also allows you to directly write Modbus RTU message over TCP socket. Is it possible to use Modbus RTU request over TCP/IP in Qt SerialBus module like pymodbus framer ?

      client = ModbusClient('localhost', port=5020, framer=ModbusRtuFramer)
