I'm right now working on final improvements of Dave Thompson's procServ
application (replacing GNU screen with a thin, stable environment for
running soft IOCs). I will be releasing this version within the next
days. You can have a look at last week's core-talk messages to get a
rough impression of what it will be doing.

Hi John,
There was a Nov 2007 thread on a similar topic:
http://www.aps.anl.gov/epics/tech-talk/2007/msg01376.php
We still use screen here and we still have the problem (I think sys$output is blocked while scrolling?) and I haven't found a workaround. I'd be interested if anyone knows of a solution.
At some point, we will look at Ralph Lange's setup:

Subject: epics IOC and gun screen and copy/scrollback mode
Dear All,
When running an EPICS IOC inside GNU Screen we have noticed
that if one
enters the copy/scrollback mode an odd thing happens. The IOC
continues
to serve channels access requests but the data acquisition itself
appears to be suspended. When someone accidentally leaves a screen
session in the copy/scrollback mode we see that the PVs in
that IOC are
effectively frozen. If you then go to the screen session and exit
copy/scrollback mode normal behavior resumes.
Have others seen this behavior? If so is there a known fix?
Regards,
