Due to the hardware abstraction layer in "modern" versions of Windows
(Windows 2000 and later), a kernel mode or "ring 0" driver is required
for memory/port mapped I/O. WriteLog has typically used direct-io but it
is 32 bit driver (Windows NT, Windows XP, Windows Server 2003) and does
not work with later, 64 bit versions of the operating system (direct-io
will not run under SYSWOW3264 - the 32 to 64 bit emulator - in 64 bit
versions of Windows).
There are alternative 64 bit kernel mode drivers - this one:
http://www.highrez.co.uk/scripts/download.asp?package=InpOutBinaries
is used by several other loggers and EXTFSK (MMTTY) for parallel port
FSK in 64 bit systems - but WriteLog can not use it.
I have not tried direct-io with Windows 7/32 (my Windows 7 installation
is 64 bit) to see if it still works there. However, absent support for
a different (new) kernel mode driver that runs on 64 bit versions of
Windows (Vista/64, Windows 7/64, Windows 8/64), Writelog LPT support
is obsolete in 64 bit versions of Windows just as parallel ports have
generally become obsolete on most new hardware.

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.

I think Steve has the right idea. Parallel ports haven't been seen on new
computers in…what…10 years? It seems time to let the technology go. (That
said, I will try to hang on to serial ports as long as possible because so
much of our ham gear needs serial ports.)
Back to your issue, I was surprised to see Steve's tale of woe. My
limited experience would tell me an internal card would be recognized by
the OS as a legitimate LPT port. And if that is the case, then Writelog
should just issue requests to the OS, which would instruct the card to
behave as we want it to. So I think it should work.
And this link says Windows 7 does support LPT ports:
http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/parallel-ports-and-windows-7/6b24de6f-6896-439a-8223-e59985907f68
I said "limited experience" earlier because I have not used an internal
LPT port in a Windows 7 computer. However, I DO have a PCMCIA dual-port
serial card adapter I use in my Windows 7 laptop. That card works fine--in
Windows 7 and also in Windows 8 for that matter. The OS does indeed see
that as two "real" COM ports.
Best of luck,

Dave - I spent DAYS trying to get my Win 7 64 bit system to interface
with
a special LPT port card I purchased for my computer for specifically CW
operation. Never could get it working even with the tech supports guys
at
the computer shop. I even have the XP alternate operating system
installed
through Win 7 and still never could do it.
Since I have 2 serial ports available I just gave up on LPT and just
wired
up serial for RTTY and CW interface. Please post your solution if you
find
one.
Thanks and good luck

Does Writelog support LPT port functions (specifically A/B focus

I have a desktop computer running Windows 7 x 64 that I want to
start using as my contest computer. I have one of these LPT
thingies on order:
