no access to tty

As quoted from <3859 at vexpert.dbai.tuwien.ac.at> by nejdl at vexpert.dbai.tuwien.ac.at (Wolfgang Nejdl):

| When I log in to our Siemens MX300 system running System V (att

+---------------

Since you're running in the "att" environment, BSD ioctls to get and/or set
the tty modes for job control will fail.  This is why you get the message.
It *should* be possible to set the BSD line discipline, thereby getting ^Z
and ^Y for job control --- try "stty line 1".  To check, type "stty all" after
the "stty line 1"; if it displays a longish stty setting list, you are in the
BSD line discipline, but if it prints "stty: unknown flag all" or similar,
then you're still in an AT&T-based line discipline.
