I'm using rtems_termios_bufsize() to change the software RX/TX fifo size of
the UART. The only documentation i found was

rtems_status_code rtems_termios_bufsize (
  int cbufsize,     /* cooked buffer size */
  int raw_input,    /* raw input buffer size */
  int raw_output    /* raw output buffer size */

But this leaves me with some doubts:

1) Is the size in bytes? I guess it is, it's just to clarify.

2) What is the cooked buffer and what are the implications of
increasing/decreasing its size?

3) What are the maximum values i can use for the buffers sizes and the
implications of increasing it?

4) How are the default values set for these buffers if i don't use
