I just recently installed windows 2000 on my vaio

there were no COM ports of which to install TO. Is there
any way to could reinstall the COM ports?

Justin...

If the modem is internal, which most likely it is, it uses a COM port, it
doesn't install on one.

You can verify what COM ports are set with debug.

From a command prompt:

debug

You should then see
-

At the - prompt, type in d 40:0 and press ENTER.
You can use q to quit debug. I need to see the first line.

It should look like this:
0040:0000 F8 03 F8 02 E8 03 E8 02-BC 03 78 03 78 02 C0 9F
...........x.x...

These are read as high byte, low byte and display COM and LPT ports
respectively.

Looking at above:
COM1: 03F8
COM2: 02F8
COM3: 03E8
COM4: 02E8
LPT1: 03BC
LPT2: 0378
LPT3: 0278

When setting up your modem, it should normally select an unused COM port and
assign it to the modem or you can select one manually. You can also test
the functionality of the modem through the property settings.

i see...hmm, like, i dont konw if it means anything, but
when i go to the modem setup wizard, it doesnt find my
modem, so i choose a standard modem, then when it says
where to set it up to, it should give me a list of the
COM ports, there are non listed, and i cant click
the 'Next' to move on to the next step. Posting that
first line you say could give you more information on
helping? or does what i just said make SOME sort of sense?

It makes sense. If it's not finding the modem, that's your issue. This
could be that the modem is set to the same COM port as your serial port. If
you look in device manager under Ports, what do you see?
