I am running Prentice-Hall's version 1.3 on a Foundation AT (an early clone). I get the spurious out-of-paper message. It is not likely that my printer (Epson FX-80) is the problem. Has anyone found a solution to this problem on other machines? -------- Dr. Eric Gossett INTERNET gossett@bethel.edu Bethel College UUCP St. Paul, MN 55112 USA TELE (612) 638-6131 -- -------- Dr. Eric Gossett INTERNET gossett@bethel.edu Bethel College UUCP

I ran into the same problem. Many video cards for compatibles use the Monochrome printer port regardless of card type. The "IBM-PC" uses two different ports; one for each type of card. MINIX relies on this difference and generates spurious "out of paper" messages when attempting to talk to a non"IBM". A fix is to include an #IF in front of the port selection logic and an #ELSE after with the port address defined as that of the MONOCHROME VIDEO PORT (since this seems to be the one used most often). Follow the whole thing with an #ENDIF. It is a change to the kernel of the system, so the system must be recompiled to effect the change. Instructions are available in "ast"'s book. The actual code is left as an exercise for the student, since all of my MINIX stuff is on its way from Germany.
