Parameters Description:
IN
= Input number or '0' to disconnect output.
'
>
' = Connection character between in and out parameters.
OUT
= Output number or '*' for all outputs.
Examples:
Switch Video and Audio input 3 to output 7
#AV 3>7
CR
~AV 3>7 OK
CRLF
Switch Video input 2 to output 4
#V 2>4
CR
~VID 2>4 OK
CRLF
Switch Video input 4 to output 2 in machine

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.
