CE_BREAK The hardware detected a break condition.
CE_FRAME The hardware detected a framing error.
CE_IOE An I/O error occurred during communications with the device.
CE_MODE The requested mode is not supported, or the hFile parameter is invalid. If this value is specified, it is the only valid error.
CE_OVERRUN A character-buffer overrun has occurred. The next character is lost.
CE_RXOVER An input buffer overflow has occurred. There is either no room in the input buffer, or a character was received after the end-of-file (EOF) character.
CE_RXPARITY The hardware detected a parity error.
CE_TXFULL The application tried to transmit a character, but the output buffer was full.
