I have a customer who moved offices from one physical location to a new one. Afterwards the Oki ML 321 connected to the SCO Open Server wouldn't print. It's connected using a parallel to RJ45 on the printer side and connects to the server via a Digi 16em. I'm a newbie when it comes to SCO or the Digi so therfore I thought that the Digi worked just like a network switch. When moving I didn't pay attention to the locations of the devices plugged into the Digi. When we got to the new location I just plugged everything back into the Digi without knowing what was what and it didn't work. The only other devices plugged into the Digi are workstations connection to the server via tinyterm to use the database software on the server and to print to the Oki plus other printers. The wokstations seem to be fine. I found out that it does matter which port is which on the Digi and that the printer is supposed to be plugged into ttyb01 (the first port on the second Digi.) I now have the printer plugged into the correct port and it still doesn't print. Thanks for your help.
