There are a few bugs in this distribution:

1) Scans hang during the first data point because in the database
'$(SHARE)/stdApp/Db/scan_3.1.db', the record that waits for
detectors to finish is wrongly configured:

grecord(wait,'$(P)Dwait_detectors') {
	field(DESC,'1 = detectors done')
	...
	field(CALC,'(A)=0')
}

...should be...

grecord(wait,'$(P)Dwait_detectors') {
	field(DESC,'0 = detectors done')
	...
	field(CALC,'A')
}

2) changePrefix313 works only on *unbuilt* directories.  In the prebuilt
directory 'xxx', PV-name prefixes currently have to be changed by hand.

3) The prebuilt Hideos IP-Octal serial support can't handle 300-baud.
(Nor can any hideos distribution I know of.  Joe Sullivan and Kurt Goetze
fixed our copy of Hideos.)

I'm not going to make a practice of cluttering up tech-talk with this
kind of detail.  From now on, patch information for the xfdApp
distribution will normally be posted only to the 'beamline_controls'
email exploder, and periodically collected on the web page.
