My pc will be replaced with a new pc using win 7 64-bit. I am testing DOSBox to see if I can run my DOS program.

I've installed DOSBox on a WIN XP computer with a parallel port.
I use a DOS program on Win XP. The program requires a "hardkey" security device to be plugged into the parallel port, then a printer.
When I mount DOSBox, the program does not see the hardkey.
How can I get DOSBox to detect the hardkey?
I don't even need to print; just have the hardkey installed between the port and the printer cable.
