The HSC TRace command enables or disables tracing of events in selected HSC 
components. 

It uses GTRACE to perform the actual tracing. The SCP TRACE command must have the 
“USR” event enabled for any trace output to result. 

For a detailed description of how to use the HSC TRACE command, refer to the HSC 
Operator’s Guide.
