| Does anyone know how I can find this info? I am connecting my video camera to a serial port and trying to access it through a com port but I don't know which com port I can use. Or which com port applies to the serial port I plugged the camera into. |

I did. There are 2 ports listed under Ports (COM & LPT) subheading:
Communications Port (COM1)
ECP Printer Port (LPT1)
But I know that the modem using COM3, but it's not listed under the ports. So I am wondering if I could find a list that shows all my ports and which ones are being/not being used. |

Sometimes with "white box" computers com port plugs aren't connected to the motherboard.
When I'm faced with a problem like this I just try com1 through com4 & see which one works. :)

This happens if your modem is a soft modem. It just emulates COM3...
I didn't know that a camera can be connected to a COM port. The bandwidth of a com port is not enough for video data transfer at all. Perhaps it is for remotely controlling the device functions (zoom etc) of course... In this case there must be a software on computer side which controls it, and it must have configuration dialogs to set the com port...

It is used to transfer still images from the camera. I WAS wondering if I could transfer video to my computer, but I guess you answered that question, without me asking it. 
But I guess I'll do what Doug does and try all the com ports. The program that comes with camera offers up to com port 10. |

| No. It only has the option to transfer still images from the camcorder to the computer. So only a serial port is needed. It stores the video on VHS tapes. |

Sorry, this is probably a bit late now, but...
You PC will usually have four COM ports, COM1, COM2, COM3 and COM4. (However, the system is capable of recognising a good number of COM ports if you install additional hardware to support them.)
COM1 and COM2 are assigned to the connectors on the back of your PC and COM3 and COM4 can be configured for additional devices (like 56K modems). Your motherboard manual should tell you which one is which.
If you're going to plug something in to the back of your PC (using a serial cable) then it will be using COM1 or COM 2 depending on which of the two ports you connect it to.
COM ports are the short ones (two of them, 9 pin, male) and the Printer Port (LPT) is the longer one (25 pin female).
COM ports 1 and 3 and COM ports 2 and 4 share an IRQ, so it's best not to attach a device to COM1 if the MODEM is using COM3 and similarly dont use COM2 if the modem is using COM4. (Hope that makes sense!)
Incidentally, I don't think the camera is going to be able to transfer video down a serial cable to your PC - serial data transfer is so slow that even the shortest clip would take ages!

D3mon, thanks for that. That's what I need to know.
And as I had said before, I am not transferring video, but still images. This is a VHS Digital Camcorder. It stores video on VHS tapes. It allows you to take digital pictures/snapshots which it stores it in it's memory. You can then transfer the images from the camcorder to the computer. |
