“S” responses
An “S” response is sent as shown below when crosspoints are switched by a command.
[CR][LF]S:<Lvl><Dest>,<Src>[CR][LF]
*
If a crosspoint is switched by an X or B command, its “S” response is sent to all terminals in the system.
However, if any crosspoints are not switched (specifying the same crosspoint as the current one), its “S”
response is sent only to the terminal that sent the command.
* C responses are sent before S responses in some cases.
* When a command is received from another terminal while a B or X command is processed, MFR units
send “S” response messages to the terminals, notifying only the latest crosspoint states.
* A crosspoint switch command is not performed if the relevant crosspoint is locked or inhibited from
changing.
