--------------------------- -------------------------------------------------------------
E_NO_ERROR No Error has occured
E_INVALID_FD Invalid file descriptor (port was not opened correctly)
E_NO_MEMORY Unable to allocate memory tables (POSIX)

E_PORT_TIMEOUT Operation timed out (POSIX)
E_INVALID_DEVICE The file opened by the port is not a character device (POSIX)
E_BREAK_CONDITION The port detected a break condition
E_FRAMING_ERROR The port detected a framing error
(usually caused by incorrect baud rate settings)
E_IO_ERROR There was an I/O error while communicating with the port
E_BUFFER_OVERRUN Character buffer overrun
E_RECEIVE_OVERFLOW Receive buffer overflow
E_RECEIVE_PARITY_ERROR The port detected a parity error in the received data
E_TRANSMIT_OVERFLOW Transmit buffer overflow
E_READ_FAILED General read operation failure
E_WRITE_FAILED General write operation failure
