NAME            kl -- KL-11/TTY-33 console typewriter



DESCRIPTION     tty (as distinct from tty?) refers to the console

                typewriter hard-wired to the PDP-11 via a KL-11

                interface.



                Generally, the disciplines involved in dealing

                with tty are similar to those for tty? and sec-

                tion dc(IV) 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 tty?) 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.



FILES           /dev/tty

                /dev/tty8       synonym for /dev/tty
