On the 4016DX (250-5001), 4020LX (250-5120), 4025LX (250-5125), 4033LX
(250-5130), and 5000MC (250-6000), the printer ports are defined 
differently with SCO Xenix release 2.2.4 (250-5200) or 2.3.2 GT (250-5203).
The chart below shows the correct port number for xenix and the port number
under the CMOS setup for the on board printer port.
