A response if 2 crosspoints are to be changed
simultaneously: C:0/0,2...L1:IA
“S” responses (Commands 1-6)
An “S” response is sent as shown below when crosspoints are switched by a command.
[CR][LF]C:<Lvls>/<Dest>,<Src>[…[S<Salvo number>][L<Link number>]]:I<ID>[CR][LF]
* If a crosspoint is switched by an X or B command, its “S” response is sent to all the 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.
* 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 to change.
