[GitHub] [incubator-nuttx] v01d opened a new issue #3418: SERIAL DRIVER WITH DMA DOES NOT DISCARD OOB CHARACTERS

[GitBox <gi...@apache.org>]

v01d opened a new issue #3418:
URL: https://github.com/apache/incubator-nuttx/issues/3418


   ```
     Description: If Ctrl-Z or Ctrl-C actions are enabled, the the OOB
                  character that generates the signal action must not be placed
                  in the serial driver Rx buffer.  This behavior is correct for
                  the non-DMA case (serial_io.c), but not for the DMA case
                  (serial_dma.c).  In the DMA case, the OOB character is left
                  in the Rx buffer and will be received as normal Rx data by
                  the application.  It should not work that way.
   
                  Perhaps in the DMA case, the OOB characters could be filtered
                  out later, just before returning the Rx data to the application?
     Status:      Open
     Priority:    Low, provided that the application can handle these characters
                  in the data stream.
   ```
