[BL] BL2 won't print or scroll in console mode

Linux prints text (cat filename.txt > /dev/lp0) on a different computer
with only one parallel port and no MDA card, and the same software as
here. Is there something I should be doing differently on a computer with
two parports? I did not need to specify IRQ 7 or anything different.
Perhaps I should have one DOS and one linux computer since all the DOS
stuff works on here. We had both parports working with DOS and Windows.
I will make sure lp1 is disabled onboard and try again here.
