Where is XPh PORT DATA kept ? - can't Delete Ports

Problem gone:

....I don't really know how, as it has been persistent for
weeks.

I added "appropriate" entries (guessing NE5 and NE6
values in some of these entries) for just TWO of my
remote printer items. My intention was to then re-boot
and go for the delete using Port tab of the dialogue.

Bizarrly, all the references I didn't want disappeared
both in this table and in the registry. Maybe there is
some stange cache and I'd tried to delete them all (???)
and it had remembered this with some flag setting - or
the act of tidying up one set of entries enabled the rest
of the code to recover and complete its actions.

FYI (incomplete set specified in original posting)
These were all the place in the registry I changed
(don't ask me what all that "S-1-5-19"-type stuff is!)
