Yes some time ago - But lost ( disk crash )
i may give you the hints:
create a new kernel task called PTTY or so.
copy most of the tty driver and modify it
i am working currently on a reimplementation of the PTTY driver.
but i need a bit of time currently for doing this if you 
have 3-4 weeks time i am probably be able to post it.

>2) has anybody implemented the select-systemcall of BSD Unix?
same as above and lost !
i had implemented it in the FS area.

the call does a `select call to any currently opened device driver
( wich is specified in the mask of the select call )
and finnally a call to the clock task for waiting.
sorry can't rember the rest.
i am **NOT** working currently at the select call.

I would like to hear also from progress in MGR development ??
