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.
The disciplines involved in dealing with tty are identical
to those for tty? and section DC(I) should be consulted.
The following differences are salient:
The system calls stty and gtty apply, and the bits in the
mode word have the same meanings, but the speed-select word
is ignored. The quit signal is generated by the key marked
`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.
