Application will sometimes crash if TCP connected device is turned off #6

If a TCP connected device is turned off, then the system reports this in the modbus library with: Error: EPOLLRDHUP or EPOLLHUP has returned true. Reconnect

Various other errors occur, then next time the application tries to perform a modbus command using the handle it crashes.
