COMPAT_43 cruft. This is supposedly the last core utility that has been using it! (So now, one should be able to remove this option from the config files. Be aware that the last officially released xterm however still requires it.) The getty has been running now for several weeks on my modem line, so i feel safe about it. Obtained from: mostly from the NetBSD vendor-branch

.Sh NAME
|

.Nm getty
|
|
.Nd set terminal mode
|
|
.Sh SYNOPSIS
|
|
.Nm getty
|
|
.Oo
|
|
.Ar type
|
|
.Op Ar tty
|
|
.Oc
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm getty
|
|
program
|
|
is called by
|
|
.Xr init 8
|
|
to open and initialize the tty line, read a login name, and invoke
|
|
.Xr login 1 .
|
|
.Pp
|
|
The argument
|
|
.Ar tty
|
|
is the special device file in
|
|
.Pa /dev
|
|
to open for the terminal (for example, ``ttyh0'').
|
|
If there is no argument or the argument is
|
|
.Ql Fl ,
|
|
the tty line is assumed to be open as file descriptor 0.
|
|
.Pp
|
|
The
|
|
.Ar type
|
|
argument can be used to make
|
|
.Nm getty
|
|
treat the terminal line specially.
|
|
This argument is used as an index into the
|
|
.Nm gettytab 5
|
|
database, to determine the characteristics of the line.
|
|
If there is no argument, or there is no such table, the
|
|
.Em default
|
|
table is used.
|
|
If there is no
|
|
.Pa /etc/gettytab
|
|
a set of system defaults is used.
|
|
If indicated by the table located,
|
|
.Nm getty
|
|
will clear the terminal screen,
|
|
print a banner heading,
|
|
and prompt for a login name.
|
|
Usually either the banner or the login prompt will include
|
|
the system hostname.
|
|
.Pp
|
|
Most of the default actions of
|
|
.Nm getty
|
|
can be circumvented, or modified, by a suitable
|
|
.Nm gettytab
|
|
table.
|
|
.Pp
|
|
The
|
|
.Nm 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 reasonably quickly.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "ttyxx: No such device or address."
|
|
.It "ttyxx: No such file or address."
|
|
A terminal which is turned
|
|
on in the
|
|
.Xr 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 file in
|
|
.Pa /dev
|
|
does not exist.
