     ttys - terminal initialization data

DDEESSCCRRIIPPTTIIOONN
     The _t_t_y_s file contains information that is used by various
     routines to initialize and control the use of terminal spe-
     cial files.  This information is read with the _g_e_t_t_t_y_e_n_t(3)
     library routines.	There is one line in the _t_t_y_s file per
     special file.  Fields are separated by tabs and/or spaces.
     Fields comprised of more than one word should be enclosed in
     double quotes (``"'').  Blank lines and comments may appear
     anywhere in the file; comments are delimited by hash marks
     (``#'') and new lines.  Any unspecified fields will default
     to null.

     The first field is the terminal's entry in the device direc-
     tory, ``/dev''.

     The second field of the file is the command to execute for
     the line, typically _g_e_t_t_y(8), which performs such tasks as
     baud-rate recognition, reading the login name, and calling
     _l_o_g_i_n(1).	It can be, however, any desired command, for
     example the start up for a window system terminal emulator
     or some other daemon process, and can contain multiple words
     if quoted.

     The third field is the type of terminal usually connected to
     that tty line, normally the one found in the _t_e_r_m_c_a_p(5) data
     base file.  The environmental variable ``TERM'' is initial-
     ized with the value by either _g_e_t_t_y(8) or _l_o_g_i_n(1).

     The remaining fields set flags in the _t_y__s_t_a_t_u_s entry (see
     _g_e_t_t_t_y_e_n_t(3)) or specify a window system process that
     _i_n_i_t(8) will maintain for the terminal line.

     As flag values, the strings ``on'' and ``off'' specify that
     _i_n_i_t should (should not) execute the command given in the
     second field, while ``secure'' (if ``on'' is also specified)
     allows users with a uid of 0 to login on this line.  These
     flag fields should not be quoted.

     The string ``window='' may be followed by a quoted command
     string which _i_n_i_t will execute bbeeffoorree starting the command
     specified by the second field.
