leon3 console driver output processing

[Espúreo Fernandez-Ulloa]

Hello Ajish,

  I also passed through a similar issue some time ago. I currently have RTEMS 4.10 with the RCC-1.2.2 version installed.

  In case you find it useful, here are part of my config:

...

#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
...

    int dev_fd;
    struct termiosnewTerm;
...
...


   /* Opening Communication devices (/dev/console_x) */ 
   dev_fd = open("/dev/console", O_RDWR);
    
   /* Get current configuration */
   tcgetattr(dev_fd, &newTerm);

   newTerm.c_lflag &= ~(ICANON|ECHO|ECHOE|ECHOK|ECHONL|ECHOPRT|ECHOCTL|ECHOKE|IEXTEN|ISIG);

   /* Local mode and receiver enabled */
   newTerm.c_cflag |= (CLOCAL | CREAD);

   /* 8 bits, enable receiver */
   newTerm.c_cflag |= CS8;

   /* Raw output */
   newTerm.c_oflag &= ~OPOST;

   /* Ignore breaks. */
   newTerm.c_iflag =  IGNBRK;
   newTerm.c_iflag &= ~INLCR; /*input modes*/

   /* Update driver's settings */
   tcsetattr(dev_fd, TCSANOW, &newTerm);
   tcflush(dev_fd, TCIOFLUSH);
}

Hope it helps,
Elias

Hello Claudio,

Thanks a lot ... Half of the problem is fixed now. '\n' is not appended 
with '\r' anymore.

But I still have the problem that 0x7D is appended with 0x5D or 0x5E. 
Where is this happening? How do I diable it?

regards
Ajish
