I discovered today that HP does it with the minor device number, too.
Both HP and IBM hide the documentation for this feature pretty effectively.
The AIX line protocols arent't discussed comprehensibely anywhere;
to figure out what's going on, you have to read the system management
guide and the VRM device driver reference.

I think you're right.  I've been successful changing both disk
partition and terminal parameters by hand.  The policy of making system
administration magic, and hiding the details from the administrator, is
annoying.  Especially when the tools provided don't do enough.  Try to
re-arrange your disk partitions using minidisks!  I've learned to use
the VRM maintenance facility, and to edit /etc/system and
/etc/filesystems by hand.  Changing simple options by editing /etc/ports
works OK.  It's also possible to change some stty options that aren't
offered by `devices'.
