getty - set terminal mode
getty [type [tty]]
The getty program is called by init(8) to open and initialize the tty
line, read a login name, and invoke login(1).
The argument tty is the special device file in /dev to open
for the terminal
(for example, ``ttyh0''). If there is no argument or
is `-', the tty line is assumed to be open as file descriptor 0.
The type argument can be used to make getty treat the terminal line specially.
This argument is used as an index into the gettytab(5) database,
to determine the characteristics of the line. If there is
or there is no such table, the default table is used. If
there is no
/etc/gettytab a set of system defaults is used. If indicated by the
table located, getty will clear the terminal screen, print a
and prompt for a login name. Usually either the banner
or the login
prompt will include the system hostname.
Most of the default actions of getty can be circumvented, or
a suitable gettytab(5) table.
The getty program can be set to timeout after some interval,
cause dial up lines to hang up if the login name is not entered reasonably
getty is started by init(8), with a process priority, umask,
limits based on the ``default'' entry in /etc/login.conf.
ttyxx: No such device or address.
ttyxx: No such file or address. A terminal which is turned
on in the
ttys(5) file cannot be opened, likely because the requisite
lines are either
not configured into the system, the associated device
was not attached
during boot-time system configuration, or the special
file in /dev
does not exist.
