I have also had problems redirecting Ada.Text_Io on the same platform.
When I use the applicable VxWorks calls, ioGlobalStdSet or ioTaskStdSet,
my printf's from C programs are redirected, but Ada.Text_Io seems to
be unaffected.  In my case, I'm trying to redirect IO to an open
socket.

The solution I'm toying with is making an Ada interface to printf.
Is there a better way to get Ada IO to respond to calls to the
above VxWorks functions?

One thing you might try, Martin, is to re-direct to "/null/0".
