Without questioning you motives there is a dirty line that you may use if you
are
willing to wait 1 sec for the result:
ash -c "busybox timeout -t 1 ash -c 'read -n0'"&> /dev/null
returns 0 on success and 143 on failure/timeout.
However, it IS hackish and I would recommend looking into the C-wrapper solution
as Laurent suggested.

Thanks a lot for that! As you may have seen in my other answer, I have to
live with a rather unpleasant occasional reboot anyway, so some hack before
doing that would not hurt too much, and neither does an additional second
waiting time.
