Purpose
This command starts horizontal scrolling on all lines. All subsequent
commands are ignored until a Scroll Mode Release command is sent.
The following list explains how the Horizontal Scroll On All Lines command
operates:
v Any codes not described here are ignored.
v The most recent Display Mode Set command becomes effective in one
screen scroll setting before the Scroll Start command is performed.
v A screen scrolls from right to left, dot by dot.
v The range of the display of being scrolled is defined by the screen mode
setting.
v The command is canceled when Pn = X'00'. After it is canceled, displayed
characters are cleared and the write-in position moves to the most
significant digit of the row.
v The command can be executed on a single line only.
v A character's Display Mode Set command (reverse, blinking, and so on)
can be added with the display data frame. If the command is written twice
or more in one scroll data frame, only the first command is valid; others are
ignored.
v When message data are changed, you must reissue this command.
While scrolling, the User Definable Font Set command is not available.
v Space data is written in the other rows except those selected with the Pl
code.
Selects the language font to use.
