Well done ! But it's rather strange that "fuser" didn't give away the
name of the culprit... As the modem-manager application seems to keep
opening and closing the ttys, you must have been unlucky and "fuser"
checked just when the port was closed...

Well, thanks to you, as there is no doubt this kind of information is
useful for everybody. We can all be victims of those little processes
launched without notice (usually at session startup time). Linux is
becoming too complicated sometimes, haha ! :-)

Good luck ! Maybe we'll have the opportunity to make a QSO via
moonbounce one day: I'm a member of F6KHM here in Brest, and we have a
nice 10.30m dish, that we use for EME too. ;-)
Best regards,
