How to allow a server on port 3690?

Would anyone have any idea why Commodo won’t let a Subversion server
(svnserve.exe) handle TCP/IP connections on port 3690? Things work
normally when I turn off Commodo’s application monitor, but of course
that’s not what I want to do. Rather, I want the application monitor
to allow svnserve to operate normally along with other apps of my
choosing. I’ve set up the application control rule for svnserve to be
as liberal as possible, to no avail. “Allow all activities for this
application” (a choice in the app control rule dialog) doesn’t do the
trick either, even when “Allow invisible connection attempts” and
“Skip advanced security checks” are also selected.
