LPT3 Should Be LPT1

No. However, I have even tried one that did and checked with a number of
manufacturers who have the most configurability (including tech support at
www.lavalink.com and and www.cablemax.com (sold thru USBGear and SerialGear)
(LPT-1284-LP, 159548, 158343, etc.)).

Since the time I posted this I have found that as of XP, Microsoft no longer
supports fully featured LPT or COM ports. According to Microsoft's article:
"Legacy I/O Removal to Advance the PC Architecture", the ability to have
IRQs, DMAs, and I/O address ranges is part of the intentional abandonment of
anything having to do with ISA architecture. This is for the embetterment of
humanity by "Removal of obsolete, slow, complicated, and often poorly
understood interfaces offer[ing] obvious benefits toward this end: simpler,
more robust machines, and a lower cost of goods." From what I can gather,
the plan is for abandonment to become more guaranteed by Vista and its
progeny.

My hypothesis is this: When COM and LPT ports are built into the
motherboard, the designers have the ability (at least for now) to add special
hardware and software in the BIOS that may still allow these ports to operate
in a relatively fully featured way. However, if you happen to have a
motherboard without them and try to add them with a PCI card, it will no
longer be possible (as of XP) to have any fully featured ones on your
computer, so just get over it. It takes about 2 person-months of labor to
reconstruct my development environment on a new machine.

Of course, this leaves me with very expensive development systems for
electronics and ICs which I can no longer support with Microsoft. I'm hoping
some creative soul has come up with some viable alternative, but judging from
what I've seen in many days of internet searches, there is no commercially
available solution.

I hope and pray someone truly proves me wrong.
