Keyboard
Overview
Keyboard data is sent to the display (as well as on-line)
when the option "LOCAL ECHO" is enabled (on) (refer to Section
5). If "LOCAL ECHO" option is disabled (off), keyboarded data is
not sent to the display (sent to line only) unless the receiver
(host) echoes the data back to the sender. Refer to Section 7
for a complete list of ASCII (American Standard Code for
Information Interchange) characters.
lOl-Key Keyboard -- 56K4l0/ACZ
The keyboard is divided into four groups of keys. The main
group of the keyboard is a standard typewriter arrangement with
some additional keys.
The fourteen keys at the left of the keyboard are system
control keys.
The eight keys across the top of the keyboard serve three
purposes. They are used as root keys (root identifier on the
front of the key), as screen-labeled keys or as function keys.
These keys provide the user with access to the modes and
features of the terminal. These keys are described in deta1~ in
this section.
The twenty-one keys at the right of the keyboard are for
cursor positioning, numeric data entry, and system control.
With the exception of keys noted below, all keys on the
keyboard repeat at approximately twenty-five characters per
second 1f depressed for more than one-half second: the
eight function keys, Break/Reset/Discon, Clear, Num Lock,
Caps Lock, the left side cluster, and the right side cluster
(the following right side cluster keys will repeat: Roll Up,
Roll Down, <-,->, and numbers when Num Lock is on).
