NAME tty -- console typewriter
SYNOPSIS --
DESCRIPTION tty (as distinct from tty0, ..., tty5) refers to
the console typewriter hard-wired to the PDP-11.
Most of the time it is turned off and so has lit-
tle general use.
Generally, the disciplines involved in dealing
with tty are similar to those for tty0 ... and
the appropriate section should be consulted. The
following differences are salient:
The system calls stty and gtty do not apply to
this device. It cannot be placed in raw mode; on
input, upper case letters are always mapped into
lower case letters; a carriage return is echoed
when a line-feed is typed.
The quit character is not FS (as with tty0...)
but is generated by the key labelled "alt mode."
By appropriate console switch settings, it is
possible to cause UNIX to come up as a single-
user system with I/O on this device.
