TTYGROUP (string) TTYPERM (string) The terminal permissions: the login tty will be owned by the TTYGROUP group, and the permissions will be set to TTYPERM. By default, the ownership of the terminal is set to the user's primary group and the permissions are set to 0600. TTYGROUP can be either the name of a group or a numeric group identifier. If you have a write program which is "setgid" to a special group which owns the terminals, define TTYGROUP to the group number and TTYPERM to 0620. Otherwise leave TTYGROUP commented out and assign TTYPERM to either 622 or 600.
