Hi Brian,StreamDevice can do this. Use a combination of @init handler and "%(ZRST)16c" redirection. See http://epics.web.psi.ch/software/streamdevice/doc/ chapters "Record Processing" -> "Initialization" and "Format Converters" -> "Types & Fields".
It might be possible that not all client applications get the enums correctly. If the client is already connected and you reboot the ioc and it starts up with new enum strings, the client might still use the old enums.

Hi all!I have a situation where I have an mbbo field that I would like to set programmatically at run time. Specifically, I would like to set ZSTR, ONST, etc... to specific values that are read back from hardware in a device driver at initialization. How can I do this from within an Asyn driver?Thanks! Brian
