        !            26: .I ttys
        !            27: file contains information that is used by various routines to initialize
        !            28: and control the use of terminal special files.
        !            29: This information is read with the
        !            30: .IR getttyent (3)
        !            31: library routines.
        !            32: There is one line in the 
        !            33: .I ttys
        !            34: file per special file.
        !            35: Fields are separated by tabs and/or spaces.
        !            36: Fields comprised of more than one word should be enclosed in double
        !            37: quotes (``"'').
        !            38: Blank lines and comments may appear anywhere in the file; comments

        !            45: typically
        !            46: .IR getty (8),
        !            47: which performs such tasks as baud-rate recognition, reading the login name,
        !            48: and calling
        !            49: .IR login (1).

        !            63: .PP
        !            64: The remaining fields set flags in the
