      Description

      QSerialPort treats EAGAIN as error.

      When using a serial port on Linux the error() signal is emitted multiple times reporting the errors: 8 (ReadError), 8 (ReadError), and 9 (ResourceError), in this order.
      Might depend on linux kernel version and/or system load and/or serial drivers used.
