Remarks

A drawing area is defined. You can then draw with a line width of n1 within the corner
coordinates xx1,yy1 and xx2,yy2.
A freely usable touch area is defined. Touch actions (down, up and drag) within the
corner coordinates xx1,yy1 and xx2,yy2 are sent via RS232.
The bar graph with the no. n1 is defined for input by touch panel.
The frame type for the display of touch keys/switches is set with n1
Automatic inversion when touch key touched: n1=0=OFF; n1=1=ON;
Tone sounds briefly when a touch key is touched: n1=0=OFF; n1=1=ON
The touch key with the assigned return code is inverted manually
The status of the switch (off=0; on=1) is sent via the serial interface.
The status of the switch is changed by means of a command n1=0=off; n1=1=on.
The touch area with the return code (code=0: all touch areas) is removed from the
touch query. When n1=0, the area remains visible on the display; when n1=1, the
area is deleted from the display.
Automatic transmission of a new bar graph value by touch input is deactivated (n1=0)
or activated (n1=1)
Touch query is deactivated (n1=0) or activated (n1=1)
Set font with the number n1 (1..16) for touch key label
n1 = X zoom factor (1x..8x); n2 = Y zoom factor (1x..8x)
Insert n1 pixels between two lines of text as additional line spacing
Text output angle: n1=0: 0°; n1=1: 90°; n1=2: 180°; n1=3: 270°;
