Running 2.1 on a 040 upgraded cube.

This happened:
	When moving some stuff the cable between 040 cube and modem got loose.
I found out about it the next morning. DTR was not on. And there was a login
process on the line. So I saw the SND and RCV lights of the modem flickering
every xx seconds (when a new login prompt was written, I suppose). Init was
spawning logins. I tried to get init to re-read the tty stuff. This did not
help (I hadn't found out about DTR yet). Then I saw the DTR light was off. I
removed the cable. I powered down (just for safety), and returned the cable to
the OTHER serial port.
	Booting now works fine, but it stops with the "Starting System
Services" view and nothing happens.

	I found out about that. I put the plug in the other serial input and
rebooted. The system came up normally (phew!).

	Now the questions:
		What happens here?
		Suppose my cable breaks. Does that mean I cannot boot my
machine proper until I have fixed that (since I am unable to change the tty
database not to try the serial until I am logged in - catch 22).

	Oh, btw, the last message is from the automounter who seems to be
unable to find his address.... Seems unlikely that it has something to do with
that, but you never know.

Thanks,
