8.54A Command display screen boundary +CDSB

27.0073GPPAT command set for User Equipment (UE)Release 18TS

Table 8.54A-1: +CDSB action command syntax

Command	Possible response(s)
+CDSB	+CDSB: <Top_Left_X>,<Top_Left_Y>,<Bottom_Right_X>,<Bottom_Right_Y>[,<Width_of_the_Boundary>] +CME ERROR: <err>
+CDSB=?

Description

The execution of this command will identify the boundary between a display area and a non-display area of the ME’s (touch) screen. If the display area of the (touch) screen is the same size as the (touch) screen, the values <Top_Left_X>, <Top_Left_Y> are set to 0, and the values <Bottom_Right_X>, <Bottom_Right_Y> match the values returned by the command +CSS (see clause 8.54).

As in clause 8.54, the x-axis and y-axis will be based on a single normal operating mode of the ME.

If emulation fails with an ME error, +CME ERROR: <err> is returned. Refer clause 9.2 for possible <err> values.

Defined values

<Top_Left_X>: integer type. Must be a positive integer representing the top left pixel X coordinate of the boundary.

<Top_Left_Y>: integer type. Must be a positive integer representing the top left pixel Y coordinate of the boundary.

<Bottom_Right_X>: integer type. Must be a positive integer representing the bottom right pixel X coordinate of the boundary.

<Bottom_Right_Y>: integer type. Must be a positive integer representing the bottom right pixel Y coordinate of the boundary.

<Width_of_the_Boundary>: integer type (the value range is in pixels, and starts at 1. The maximum value is implementation specific). Representing the width of the boundary, by default the width is 1 pixel. If the integer value is positive, the boundary is part of the display area of the ME’s (touch) screen. If the integer value is negative, the boundary is part of the non-display area of the ME’s (touch) screen.

Implementation

Optional.
