No, on ttyS2 there is a serial Terminal (VT320), so this is O.K. But I found the problem: It was modemmanager, which was _automatically_ installed. Modemmanager screwed up ttyS3 and ttyS2 (perhaps the onboard ttyS0 and ttyS1 also, but I can’t tell, because there is no device on ttyS0 and ttyS1 does not even have a connector). Probably systemd/modemmanager/dbus assumes that there must be a modem understanding AT-commands behind every serial interface. Uninstalling modemmanager does the job.
