[WriteLog] LPT on 64 bit OS?

That's not true.  Windows 7 (and Windows 8) - both 32/64 bit versions
support native parallel ports.  I have a couple systems with LPT ports
on the mainboard that are recognized and used by Windows.  However, no
version of Windows from NT on includes a kernel mode driver to permit
port mapped I/O (direct control over the port "bits").  A third party
driver has always been necessary - the difference is that Writelog does
not recognize those drivers where other loggers all appear to have
settled on InpOut32 which works with both 32 and 64 bit systems.

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.

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.
