INTRODUCTION
The HP 2624A keyboard is a separate unit that is linked to
the display portion of the terminal by a flexible cable.
Included within the keyboard unit is a speaker that is used
for sounding the terminal's bell tone. Except for two keys
( _ and _ ) , the overall keyboard can be logically
divided into the following five functional groups:
• Character Set Group. The layout of these keys is
similar to a standard typewriter keyboard. In addition to
the alphanumeric character keys, this group includes
typical data terminal keys such as
mil
and
III .
• Numeric Pad Group. This group is a calculator-type
numeric key pad and is located to the right of the char-
acter set keys. You may use this pad for entering large
amounts of numeric data such as that required for finan-
cial reporting.
• Cursor Control Group. This group is used for moving
the cursor around (up, down, left, right, tab, and back
tab) on the screen and for controlling what portion of
display memory appears on the screen (home, roll up, roll
down, previous page, and next page).
• Edit Control Group. This group is used for inserting
and deleting characters in relation to the current cursor
position (insert character, delete character, insert line,
delete line, clear line, and clear display).
• Function Key Group. This group includes the eight
keys labeled
"f
1 "
through
"fa"
and the keys labeled
"AIDS", "MODES"
and
"USER KEYS".
The . - _ keys
are multipurpose keys in that the functions they perform
vary from one situation to another. At any given time the
applicable labels for the function keys are displayed
across the bottom of the screen (figure 3-1).
SELECTING MODES
Pressing the
II
key enables the mode selection keys and
changes the •
- _ screen labels to the following:
............
-
LINE
MODIFY
BLOCK
REMOTE
TERM
MEMORY DISPLAY AUTO
MODIFY
ALL
MODE
MODE
TEST
LOCK
FUNCTNS
LF
Except for the
"TERMI HAL TEST"
key (which initiates the
terminal self-test), these keys act as toggle switches in that
they alternately enable and disable the designated mode.
When a particular mode is enabled, an asterisk appears in
the associated key label.

Remote/Local Modes
When a communications link exists between the terminal
and a remote host computer the terminal is in either of the
following two modes:
• Remote Mode. In this mode, when you press an al-
phanumeric key the associated ASCII code is trans-
mitted to the host computer.
• Local Mode. In this mode,
~hen
you press an al-
phanumeric key the associated character is displayed at
the current cursor position on the screen (nothing is
transmitted to the host computer).
From the keyboard, you switch the terminal back and forth
between local and remote modes using the
"REMOTE MODE"
(,,)key.
From a user-definable key you can switch the terminal
from local to remote (and vice versa) using the following
escape sequences:
Local:
<ESC>&kOR
Remote:
<ESC>&k1 R
A remote/local mode designator is maintained in non-
volatile memory. When you change modes using the
"REMOTE MODE"
key, you also alter that mode designator in
non-volatile memory. When you change modes using the
escape sequences, however, the designator is NOT altered.
