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 to open for the terminal (for
example, ''.ttyco''). If there is no argument or the argument 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 gettytab5
database, to determine the characteristics of the line. If there is no
argument, 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 indi-
cated by the table located, getty will clear the terminal screen, print
a banner heading, and prompt for a login name. Usually either the ban-
ner or the login prompt will include the system hostname.
Most of the default actions of getty can be circumvented, or modified,
by a suitable gettytab table.
The getty program can be set to timeout after some interval, which will
cause dial up lines to hang up if the login name is not entered reason-
ttyxx: No such device or address.
ttyxx: No such file or address.
A terminal which is turned on in the ttys 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 device does not
