SSS Command in the Extended X Language
The SSS command is an undocumented command in the Extended X Language (SX). This software switch command will cause the SX to jump to the Fault/Kill Sequence, which is defined by the XFK command, when one of two conditions happen:
If the stop command, S, is issued to the SX.
If a stop input, defined by
IN{n}D (where {n} is the number of the input), is activated.
NOTE: This command is only valid from Software Version -F2 or later.
