specific control codes recognized by the ADM 3A
are described. Procedures are provided on how to

KEYBOARD OPERATIONS
The operator uses a keyboard very similar to the
keyboard of a standard typewriter to enter data.

displayed on the CRT screen immediately (if in
half-duplex mode) or as an echo from the remote
computer (if in full-duplex mode).
Figure 3-1, page 3-2 shows the layout of a
standard ADM 3A keyboard. Functionally, the
keyboard consists of displayable character keys
and special function keys. Some of the special
function keys can also be used in conjunction with
certain displayable character keys to command
specific control operations requiring
simultaneous depression of two keys.
In the standard ADM 3A, 96 characters are
displayed. These characters include upper and
lower-case letters, numbers, punctuation marks,
and most symbols.
