Input properties
The following commands are setting up the properties of the input ports. If only one or a
few parameters have to be modified, the protocol enables to mask the other parameters,
so they can stay untouched. To mask a parameter use “x” or “X” as its value.
Example:
{:ANALOG#2@SI=x;x;x;x;210;x;} Only change the horizontal position on the
input port 2.
