Hi Brian,

The asyn driver does not have access to the record.  The driver only
talks to device support, and the device support talks to the record.

I don't think you can do what you want using standard asyn device
support.  But if you wrote your own device support for the mbbo record
(based on the mbbo support in devAsyn/devAsynInt32.c for example) you
could use the asynOctet interface to query the driver for the enum
string values during initRecord, and set those enum string values in the
record.

Subject: Asyn driver access to PV fields.

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
