It is case sensitive and thus surprisingly strict for an OS that seems to do uppercase only... Good to know. Being a unix guy I probably would have assumed case sensitivity. :) What is regex?? Regular Expressions. A pain in the ass to learn but totally worth it. Circuit names for ethernet device are DDD-N DDCMP (serial lines), CI and DSSI devices are DD-N-M Where D is a letter and N and M are digits. Ok, so I see a trend here. All circuit names have a dash in them. That's how I was going to filter them out but I think I found a better way. Thanks!! -brian
