I wonder if we might not want to just retire comcontrol entirely. This one feature is the sole-surviving remnant from the 386BSD patchkit driver that Christopher G.

I had totally forgotten about it since I think I last used it in the 90s... and even then it was for a custom serial device the hw engineer fixed to not need it.
