[WriteLog] LPT on 64 bit OS?

[Dan Karg]

I don't have this under Win7 however under WINXP I did find that even
thought the LPT port looked like an normal LPT port to the OS, the real
hardware address of the port was not at your normal address's 0x378/0x278
etc. Instead I found my hardware at a much different address (look in
device manager)
Once I put the real hardware address into writelog.ini (LPT1=0xDCD8 in my
case) , and setup a proper port pass thru driver (I use AllowIO) it worked
like a champ.
This had me stumbling for quite a while and I had tried a number of
supposed 'real' LPT ports before figuring this out.
Again this is under WinXP, not tried under Win7 but might be the same.
