Terminal Status
Change N/A 1 byte Query only.
Indicates if there has been a change in the
configuration since the last time the command was
given. A value of 0 indicates no status change, and a
value of 1 indicates there has been a status change.
A status change is defined as any time a parameter is
changed. Such as when command is successfully
executed that changes a value. A status change also
results when there is a redundant switchover, or a
fault condition. A query does not set the status
change flag. The status change flag is cleared after
being read.
Example: <1/TSC?’cr’
>0001/TSC=0’cr’’lf’ TSC= TSC? TSC=x
