Switching an input <in> to output <out>. Following commands with A, V, AV parameter value can take effect
in multiple layers, according to their parameters. Depending on 'A' or 'V' it can change only the Audio or only
the Video layer; or 'AV' changes both. #crosspoint

INFO:
The <layer> parameter usually can be skipped for legacy purposes. In this case, the devices change
all (Video & Audio) layers but using status commands it displays information about only the Video layer.
Please use AV option, when available.
Example 1
 {2@1 AV}
 (O01 I02 AV)
I2 audio and I2 video input ports are switched to O1 output port.
Example 2
 {0@1}
 (O01 I00)
ATTENTION!
The response of this command does not show if the output is muted. To check the mute
status a separate query has to be used like {VC}.

ATTENTION! Analog video inputs does not contain embedded audio. If you use the AV option in case of
VGA input (I1) the audio will be switched to the analog audio input 1 (I1) and in case of DVI-A input (I5) the
audio will be switched to the analog audio input 2 (I5).
