[WT-support] How To Use LPT Port with Windows-7 64-Bit (Addendum)

One important step in getting the LPT Port to work in Win-7 x32 or x64 is to
specify the proper Port Address in:

       Options > Configure Interfaces.> Configure Printer Ports  

The Port Address in Default Win-Test Configuration is 378h.  This is the
original MS-DOS I/O Address for LPT1.

I'm think that people running Win-7 x32 or x64 will have fairly new PC's.
If your PC Motherboard has an On-Board LPT Port, there a good chance it will
be on 378h.

However, many new motherboards lack a LPT Port.  In that case the LPT Port
will have to be added with either a PCI or a PCI-Express add-on card.  In
that case, the LPT Port will use an entirely different address.  To properly
configure the Win-Test LPT Port Address, first determine what it is):

1) Click on Control Panel > Device Manager
2) Expand the PORTS (COM & LPT)  section by click on the "+"
3) Double-click on the PARALLEL PORT
4) The click on the RESOURCES Tab
5) You see something like:

       I/O Range   DFE8-DFEF
       I/O Range   DFE0-DFE7
       
6) Pick the first Hex Number (DFE8 in the above example) and enter that into
   the Win-Test Printer Port Address Dialogue Box
