I. Special Keys Used To Change The General Runtime Functionality
|
|
=====================================================================
|
|
|
|
|
|
CTRL-F9 Function key labels ON / OFF
|
|
------------------------------------
|
|
|
|
this key is only operational, when in HP/VT mode, see CTRL-F11
|
|
|
|
CTRL-F9 toggles between function key labels displayed or not.
|
|
|
|
ON: screen has either 25-3 = 22, 28-3 = 25 or 50-3 = 47 lines
|
|
2 lines fkey labels displayed
|
|
row/col display enabled
|
|
1 line status/load avg line
|
|
|
|
OFF: screen has either 25-3 = 22, 28-3 = 25 or 50-3 = 47 lines
|
|
no function key labels displayed
|
|
no row/col display
|
|
no status/load avg line
|
|
|
|
applicable escape sequences:
|
|
|
|
switch OFF:
|
|
ESC & j @ remove labels from screen
|
|
|
|
switch ON:
|
|
ESC & j A display system fkey labels
|
|
ESC & j B display user fkey labels
|
|
ESC & j C display current fkey labels
|
|
|
|
|
|
CTRL-F10 User / System Function key labels
|
|
-------------------------------------------------
|
|
|
|
this key is only operational, when in HP/VT mode, see CTRL-F11
|
|
|
|
CTRL-F10 toggles between the display of user or system
|
|
function key labels
|
|
|
|
this key is only active if labels are toggled on via
|
|
the CTRL-F9 function key
|
|
|
|
screen has either 25-3 = 22, 28-3 = 25 or 50-3 = 47 lines
|
|
2 lines fkey labels displayed
|
|
row/col display enabled
|
|
1 line status/load avg line
|
|
|
|
|
|
applicable escape sequences: (see above)
|
|
|
|
ESC & j A display system fkey labels
|
|
ESC & j B display user fkey labels
|
|
ESC & j C display current fkey labels
|
|
|
|
|
|
CTRL-F11 Toggle between pure VT and HP-VT Emulation
|
|
----------------------------------------------------------
|
|
|
|
This key switches between pure vt100/vt220 mode and
|
|
vt100/vt220 with hp-fkey-labels mode of operation.
|
|
this is not dependent of any screen resolution the
|
|
virtual consoles are in.
|
|
|
|
initially, after power on, all virtual screens are in
|
|
the pure vt-mode:
|
|
|
|
- the emulator does not execute any hp escape sequences
|
|
- the function key label lines are switched off
|
|
- no load average or status line is displayed
|
|
- no row / column counter is displayed
|
|
- the full screen 25x80, 28x80 or 50x80 is usable
|
|
- CTRL-F9 and CTRL-F10 have no function
|
|
|
|
when toggled to the vt/hp mix of operation, the following
|
|
changes take place:
|
|
|
|
- the emulator executes the supported hp-esc sequences
|
|
- the function key labels are displayable depending
|
|
on the state of CTRL-F9/CTRL-F10
|
|
- the load average is displayed
|
|
- the row / column counters are displayed
|
|
- in any screen resolution, the last 3 lines are lost,
|
|
so one has a 22x80, 25x80 and 47x80 resolution
|
|
- CTRL-F9 and CTRL-F10 are operational.
|
|
|
|
when switching modes by means of CTRL-F11, the following
|
|
changes to the current environment, the emulator may
|
|
be in, apply:
|
|
|
|
- the screen is cleared
|
|
- the cursor moves to the home position
|
|
- the scrolling region is reset to default
|
|
|
|
(this functionality is available via an ioctl)
|
|
|
|
F5 Cycle current page
|
|
--------------------------
|
|
|
|
This key cycles through the display of the video
|
|
pages. on startup, page 0 is displayed; with every
|
|
keypress of F5, the next page is displayed, wrapping
|
|
from the maximum page number back to page 0.
|
|
|
|
F1 switches to page 0
|
|
F2 switches to page 1
|
|
F3 switches to page 2
|
|
F4 switches to page 3
|
|
|
|
Shift-F1 -- select screen 4
|
|
Shift-F2 -- select screen 5
|
|
Shift-F3 -- select screen 6
|
|
Shift-F4 -- select screen 7
|
|
Shift-F5 -- select (current screen - 1)
|
|
|
|
(this functionality is available via an ioctl)
|
|
|
|
|
|
II. Special Keys used to change the Runtime Functionality of a Page
|
|
=======================================================================
|
|
|
|
when in mixed HP/VT mode, one has two types of function key labels
|
|
on screen, user function keys and system function keys. they are
|
|
accessed by using the CTRL key while pressing a function key.
|
|
|
|
the function key labels are NOT available in pure VT220 mode--although
|
|
the function keys are still active
|
|
|
|
the user function keys and their labels can be reprogrammed by use of
|
|
escape sequences.
|
|
|
|
in system function key mode, several pre-programmed functions inside
|
|
the emulator can be toggled, currently implemented are:
|
|
|
|
- CTRL-F1, toggle 80/132 columns
|
|
- CTRL-F2, soft reset emulator
|
|
- CTRL-F3, toggle force 24 lines mode
|
|
- CTRL-F4, toggle keyboard debugging (if compiled in)
|
|
- CTRL-F5, toggle the audible beep generation
|
|
- CTRL-F6, toggle 7/8 bit char width
|
|
- CTRL-F7, toggle display functions. this means that control codes
|
|
in the range 0x00 to 0x1f are not EXECUTED by the emulator
|
|
any longer, but displayed on the screen
|
|
- CTRL-F8, toggle automatic cursor wraparound at end of line
|
|
|
|
these functions operate just for the selected page
|
|
|
|
|
|
III. Keyboard VT220 compatibility
|
|
====================================
|
|
|
|
The following keys behave different as probably expected.
|
|
|
|
They were mapped to provide more VT220 compatibility.
|
|
|
|
|
|

|
|
ALT-Keypad-3 popular boot loader in mind
