SECTION 2 " RT3210 Radio Terminal
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 2-3
As the cursor moves within the window, the radio terminal’s
display window moves to keep it centered. When the cursor
moves off the right, left, top, or bottom edge of the VT220
terminal’s display, the window remains fixed despite the
cursor’s movement.
Corner Mode
Corner mode begins with the window in the upper left cor-
ner of the larger VT220 terminal. It keeps the cursor in the
lower right corner of the display. Corner mode works best
for applications that use the upper left corner of the logical
screen.
As the cursor moves off the right or bottom edge of the radio
terminal’s display, the window moves to show the cursor.
When you use corner mode with the [FUNC] or [ALT] key,
you can move the cursor a predetermined number of key
presses in all four directions.
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 go beyond an outside boundary, an error tone sounds.
