yess, I agree, but hopefully this has been explained by the National Semi's
datasheet :(

it unlocked the port fine, however, it just seemed to make no difference to the
logsi generated. hurmm....makes me think that linux is not addressing the port
right, but more than that i cant say.

i know that the versions are different, but i cant believe that the dosemu
teamchanged tracing all that much. {quick check through the initialisation
Hurm, surely the info you need _is_ there, there is def. reads to port 3f0 and
(parts of my parallel port range) and also the reads to / from ports before

anyway...will try and download the dosemu version you want an compile it....
this might take some time (due to real work calling :(
