This seems fairly general and worthwhile. I found some info here:
http://www.lothosoft.ch/thomas/libmip/markspaceparity.php

I would change "stick" to "constant" in the patch probably.

Also I remember this recently in passing on lkml...
http://article.gmane.org/gmane.linux.usb.general/96740
which references:
http://comments.gmane.org/gmane.linux.kernel/1584028
which only adds C_CMSPAR(tty) as an internal define now,
which hints that this might not be well supported generally?

thanks,
Pádraig.
