Is there any IOC shell command (or some way) that allow me do things like "dbpr external_PV" or "caget external_PV"?

Thanks,

I am not aware of any IOC based tools that support this *directly*. It would be a useful utility if you chose to develop it.


However, there is always the hack!

If you have a spare record in your IOC (e.g. a soft AI record) you could ...

dbpf "softAI.INP", "externalPV"
dptr "softAI"

The STAT field will reflect if the external PV was found, the .VAL will reflect its value.
