Scrolling Mode
The Kyman™ has a CGA compatible display adapter and allows the application to
write on a virtual 25 lines by 80 columns display. On the other hand, the user can see
only a portion of this virtual display at a time, which we call the physical display.
The "scroll" parameter controls which portion of the virtual display is seen by the
user.
Fixed the physical display follows the cursor vertically, long lines are
automatically wrapped. The keyboard has no effect on the physical display
position.
Virt the physical display follows the cursor vertically; by enabling the "scroll
control" mode the arrows allow both a vertical and horizontal scroll of the
logical display.
Track the physical display follows the cursor both vertically and horizontally; by
enabling the "scroll control" mode the arrows allow both a vertical and
horizontal scroll of the logical display.
Software the physical display position is fixed. It can be moved only by the
application software.
The "scroll control" mode is not the same as the scroll parameter
and is not selected in BSETUP but using the keyboard sequence
described in par. 4.3.3.
NOTE
Keyboard Status/Battery Low LED
This is a bi-colored LED. The red color always signals a low battery condition while
the meaning of the green color can be selected as follows:
The "User" value causes the green LED to be managed by the application program.
The "Alpha" value causes the green LED to be lit when the keyboard is in Alpha
mode.
The "Scroll" value causes the green LED to be lit when the keyboard is in "scroll
control" mode.
