The vast majority of the drivers we ship are full duplex, but it's possible
that the applications concerned might not be getting this information. Many
recent commits have happened in this area, particularly with regard to
Linux emulation.

I'd suggest browsing the source code or using ktrace to determine which
ioctl(s) the affected applications are using (or failing to use).
