Manual Row Mapping and Control
For most OSD displays the POPSET, POP ROW SEL,
FLIP, TEXTSET and RETURN commands should be used
to control row positioning.
TEXTSET mode provides automatic row allocation from
top to bottom of the screen with all rows continuously vis-
ible. Additionally, TEXTSET screens have a definable ver-
tical window size and position and support automatic text
scrolling at the bottom of the window.
