5.3.4 ECU 3.20 or earlier on SCO collides with mgetty

ECU releases 3.20 and earlier had a severe bug in the utmp handling that prevented dialing out on a port that mgetty uses. It has been fixed in ECU 3.27. If you run into that problem, please get a newer release. Alternatively, you can use the patch that Uwe Fuerst provided, it can be found in patches/ecu320.p1.
