Cord conversion

[DisplacedCanuck]

I am in the process of upgrading an audio recording computer from, a Windows 2000 to XPx64. Unfortunatly, the audio i/o card manufacture (Digicart) doesn't offer drivers for the XPx64. I was thinking about using a Creative X-Fi sound card. The only problem I've run into on that is that the XLR, there are two input and two output, to serial cord has a 15 pin output while the card only has a 24 pin serial input.
Are there any adapters or pin layout so I can properly create a cord?
Any input would be most apprieciated.
Thank you.

I'm not sure if this is where this question would go now that I recently found out that what I am trying to do is convert a db 15 serial port female to a AD_Link 26 pin serial port male.
Does anyone know where I can find a pinout description/image for both of these? I would like to save money by making it myself.
Are there are any retailers that would sell such a thing?
Again, thank you in advance for any information.
