Subject: Waveform record help
From: "Erik Johansson" <[email protected]>

Hi all,

This is a simple question, but all our resident EPICS experts are out on
vacation, so I am appealing to you all:

If I bypass all EPICS db routines and fill the contents of a waveform
record by writing data directly to the BPTR address and then perform a
caget on the record, I get all zeros returned, regardless of the data
written. Why? What can I do so that caget returns the actual values in
the record? Note that I am doing this for debug/troubleshooting purposes
during system integration only.

Thanks,

Erik
