As a side note, there is at least one other OS that does a similar thing 
-- SCO XENIX allows one to open a port with a (minor#+128) without 
carrier detected.  The FAS driver for SysV based UNIX versions has a 
comparable minor device -> port behavior setup.  I'll support such an 
idea in NetBSD unless there is a good philosophical reason against it.
