I have a little program I wrote to rearrange the LPT entries so that
they made sense for my purposes.  I include it here in its entirety,
but I don't know how well it will work in NT.

Most certainly.  Like I said, it's emulating hardware.  The 9x series
is more likely to show you the real hardware.  And you should always
use the BIOS calls if they serve your purpose, but you'll still have
the 3bc/378/278 issue.

cseg    segment
        assume  cs:cseg,ds:cseg
        org     100h

start:
        mov     ax,40h
        mov     ds,ax
        mov     ds:[8],378h
        mov     ds:[10],3bch
        mov     word ptr ds:[12],0
        mov     word ptr ds:[14],0
        mov     ax,4c00h
        int     21h

cseg    ends
        end     start
