Help!

I wrote a DOS installable device driver and would like to make
it usable under OS/2. (I don't know anything about OS/2 expect that
there is some DOS capability, DOS in a window?) Someone told me
that OS/2 doesn't support IOCTL read and write! Is this true?
What happens when a DOS program in an OS/2 window generates an
int 21 for IOCTL read or write? Is there a good reference for
writing device drivers for OS/2 that can run, or at least be 
compatable with drivers for DOS?

Thanks in Advance!
