Try telling the "lpt" layer that a printer port lives at 0xb000.
See if that just happens to magically work. (I'm too lazy to go and
read the manuals for you, but you should be able to figure it out
by yourself......)
Then, suppose that it works, you will have to guess where the second
one lives:
0xb004
0xb008
0xb010
0xb020
0xb040
Are the most likely candidates.
