When I log in to our Siemens MX300 system running System V (att environment), each csh shell gets the message: "no access to tty; thus no job control in this shell". I do not have these problems, when I use the ucb environment on the MX300, or if I work on our SUN's. Does anybody know, what causes this message? -- Wolfgang Nejdl nejdl@vexpert.dbai.tuwien.ac.at Technical University of Vienna vexpert!nejdl@relay.eu.net Paniglgasse 16, A-1040 Vienna, Austria ...mcsun!tuvie!vexpert!nejdl

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. ++Brandon -- Me: Brandon S.
