lpt bi-directional support

Currently I have software running on a windows xp machine.  The company that supplies the software has hardware that connects to the parallel port which holds the license key for the software.  When I install windows 2003, the comapnies software cannot find the hardware on the parallel port.  This works fine under XP.  Are there any additional security settings on Windows 2003 that would stop the software from finding this hardware.  Windows 2003 finds a printer when it is connected to the parallel port but I was told this piece of hardware requires bi-directional support.
How can I adjust the settings on the Parallel port to be more open.

Thank you!!

Did you make sure that bidirectional support for the parallel port is enabled in the BIOS of the 2003 machine?

When I am in the BIOS of the 2003 machine these are the only options I have...

Parallel Port Mode:  SPP, EPP, ECP, or ECP+EPP...

I tried all four of these.

But nothing that states bidirectional support...
