Dear Axel Dörfler,
Thanks for your comment and document.
I'll more than happy to re-factoring the tty layer with following ideas
- usable by other devices
- not necessary compatible with BeOS
How about architecture of this the new tty layer? Do we have a master design
or I have to following some guidelines to make it work with others
part software or current working device drivers.
Regards,
Ha

First of all, it's just called device manager; the "pnp" has been
discarded ages ago. And then, there is a device node tree with
parent/child relations.
