command to open a cd tray?

Is there a command in OpenBSD to pop out a cd tray, and another one to
detect when it was closed?  An added bonus would be to detect if there
was a disk still in the drive after closing.

This is pretty trivial and stupid, but the idea popped in my head and
I was curious.  I'd prefer the command be available in a stock openbsd
build, or if perhaps a tiny stand alone executable.  Otherwise I won't
waste my time looking.
