io-char handling of errors

QNX DEVELOPERS Realtime and Embedded

Hi

I want to know how the io-char handles the various errors like, parity error, Brake Interrupt error, overflow error, etc. There is nothing mentioned about handling of these errors in the documentation.

Does an application gets to know that these errors have occured or io-char simply ignores the received character with error or does io-char handles them case-by-case and if yes then how?

thanks in advance :slight_smile:

I don’t think it is io-char that handles these directly, but rather the driver. In QNX 4 you could get notification of the error with the proper stty setup, but I haven’t played with the QNX 6 version of this feature.
