NAME
ttys - terminal initialization data
DESCRIPTION
The _t_t_y_s file is read by the _i_n_i_t program and specifies
which terminal special files are to have a process created
for them which will allow people to log in. It contains one
line per special file.
The first character of a line is either `0' or `1'; the
former causes the line to be ignored, the latter causes it
to be effective. The second character is used as an argu-
ment to _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. For
normal lines, the character is `0'; other characters can be
used, for example, with hard-wired terminals where speed
recognition is unnecessary or which have special charac-
teristics. (_G_e_t_t_y will have to be fixed in such cases.) The
remainder of the line is the terminal's entry in the device
directory, /dev.
