An RTEMS call exists in termios to change the default buffer sizes. I
have found this has helped in the past. The call is defined in
'rtems/libio.h' and is:
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 */
);
Note: The new buffer sizes only effects a tty opened after the call is
made. It does not try to change the size of open ttys.
