Seems, that I have more luck than you, my modem only hangs, let's say,
once every two months, if at all.

Yes, at least for Linux, that's normal behaviour, because no process is
using the line, so no DTR is asserted. Maybe my problem is different from
the one discussed here, because
	a) it appears less often.
	b) CTS is high (according to the LED)
Mgetty can't reset the modem, and apparently the modem can't/does not/whatever
send RING? I will try the procedure of calling the modem myself next time
it hangs, so I can't tell by now.
