Subject: RE: CSS Text entry values not updating on PV change

The driver is based on Stream Device, but I was able to update the records using OUT fields.  My problem turned out to be that I was setting a PV with name "GET", when I should have been setting a PV named "SET".  Once I did that, the values updated when I refreshed the OPI.

Thank you,

Iain.
