BSP for AT91SAM9263-EK

[Johannes Schock]

I use the termios system.
I think the per character basis is caused by the print code used by
Ticker. The code uses several printfs as putchars (buffer_test_io.h):

  #define puts(_s) \
      do { \
         printf( "%s\n", _s ); \
      } while (0)

  #undef putchar
  #define putchar(_c) \
    do { \
       printf( "%c", _c ); \
    } while (0)
