for Coordinate A individually. The commands SnnPAXxxxx and SnnPAYyyyy
perform the same functions, but this form of the command can also set Coordinate
B, for example SnnPBXxxxx or SnnPBYyyyy.
If it also possible to set both x and y in a single command for Coordinate A or
Coordinate B with the commands SnnPAxxxx,yyyy and SnnPBxxxx,yyyy
respectively. For all Graphic Field position commands, the parameters xxxx and
yyyy can be from 1 to 4 digits in length and may optionally be prefixed with zeros.
For example, sending S4X0200 and S4Y0400 sets the field position to (200, 400).
Changing the text position does not automatically update the video output.

Each Graphic Field has a Line Color specified by Red, Green, and Blue
Components in the range from 0 to 255. The Line Color is used for solid
rectangles, for the outline of open rectangles, for corner markers, target markers,
and the foreground of text.
The colors are entered as three Serial Commands by sending a Red, Green and
Blue Serial Command. For example: sending S1R220, S1G025 and S1B250 sets
line color to purple.
The default color is white (R255, G255, and B255). Changing the text color does
not automatically update the video output.
The Line Color has a transparency property that can be controlled using the
S1Aaaa command to set the alpha value for mixing with underlying layers. Setting
the alpha value to 0 sets the Line Color to be fully visible and no content on lower
video layers will be visible through the Line Color. An alpha of 255 sets the Line
Color fully transparent. At this setting the color will be completely invisible.
For example: sending G1A192 makes Field 1 approximately 75% transparent.
Changing the text transparency does not automatically update the video output.
