Are you using real RTEMS 4.10 from rtems.org, or the Gaisler port of
RTEMS. There are substantial differences in hardware drivers.
The APBUART driver from original RTEMS 4.10 (/dev/apbuart0, etc.)
is not based on Termios as far as I know. So VMIN/VTIME stuff will
simply not work.
I wrote a Termios driver for APBUART a few years ago which supports
non-blocking I/O. Not sure that it still works with current RTEMS.
Feel free to try this if you think you can use it
I should maybe try to get this merged in RTEMS. The problem is this
code is not backwards compatible with the current APBUART driver,
precisely because it is Termios based.
