Are you sure you don't have some other hardware that
offers a virtual serial port ? Maybe the port on your Siig
PCI card is just not bound to the OS for some reason.
Is the cable connected to the header correctly ?
Unless the connector is keyed, I suppose it is
possible to rotate the ribbon cable connector,
which would screw up the pinout.
There is a company called FTDI that makes USB devices
that other companies design into their hardware. I
believe some of their chips gain there interface, by
declaring themselves as virtual serial ports. So
some product that uses one of the FTDI chips, might
interfere with your real COM port usage.
There is a picture of Device Manager at the bottom
of this page, showing how some serial ports get listed:

There is more fun with Device Manager here. Like how to
get hidden devices to show up:

Another option would be to use SiSoftware Sandra or
Lavalys Everest, and take a look at your hardware
inventory. There must be an explanation in there
somewhere. (You can get Everest here.)

Just a guess,

That'll give me a lot to think over. Unfortunately, the doc, I found it
yesterday, is just chapter two, and has no hardware diagrams to speak of
that might address jumpers. I'll take a look at the URLs. I think I have
Everest, but not on the machine in question.
I have three serial devices I'm dealing with. The newest is a motor that
drives the focuser on a telescope, and it's what caused me to go to the
second siig serial port. Another is the modem, and the last is a connection
to the drive on the telescope. Probably the fourth serial port is the
keyboard or some common device on the computer, maybe the mouse.
As I was examining your response, we had "The Perfect Power Outage", as I
describe below when I later described it to some friends. Your response was
the page mentioned below.

A strong storm has moved into N. California today. This morning forecasts
were for thundershower activity (pretty unusual here) in the afternoon.
Around 11 am I disconnected some sensitive electrical equipment when I heard
some light storm static on the AM radio. I continued to access the internet,
and made some copies on my copier. I was reading some e-mail and decided to
print it. As the page fell into the hopper, the power went out everywhere,
and then came back on in 10 seconds. I looked at my watch and started
laughing. The time read 12 noon. No clocks to update.
