commands* #AV 1>* | V 3>4, 2>2, 82>1, 0>2 |V 82>3| A 0>1 | V? * CR

First switch all Audio and video outputs from input 1,

Then switch video input 3 to output 4, video input 2 to output

2, video input and disconnect video output 2.

Then switch audio input 3 to output 2,

Then disconnect audio output 1.

Then get status of all links (assume this is 4x4 matrix).

Commands processing start after entering CR, response will sent

for each command after processing it.
