Page Mode
Page mode provides predefined pages within the larger
VT220 terminal. The size of these pages depends on the
number of rows and columns selected for display. The radio
terminal moves the window by a multiple of the page size.
As the cursor moves off the edge of the radio terminal’s dis-
play, the window changes to the next page.
Lazy Mode
Lazy mode starts the cursor in the upper left corner of the
display. The cursor moves across the display in the scrolled
direction. When the cursor goes beyond the edge of the dis-
play, the data begins to move in the scrolled direction and
the cursor remains at the edge of the display. When you try
to move the cursor beyond an outside boundary, an error
tone sounds.
Screen Lock Mode
Screen lock mode allows a specified screen size to be set up
and locked. Only the commands issued to the selected
screen size are operated on. For example, if the host sends
characters to the display, and the number of characters to
display is greater than the number of columns specified, the
last column(s) on the screen are overwritten.
Locked Mode
If locked mode is selected through the firmware menus, the
view window is locked to the upper left-hand corner of the
display. The screen does not window around, and only the
area that has been selected to be the screen size is visible.
Locked mode disables the windowing keys, or only allows
you to window around the physical display size selected
through the firmware menus.
