Unable to Identify a Computer Port Icon

I tried looking this up in Gateway’s documentation and on Google to no avail. I’m wondering if someone could tell me what a certain computer port icon means so that I know what the port is actually for. The icon is the one at the top and middle of the image at http://www.frontx.com/diy_icon.gif.

 

Middle of the top row. Serial (COM) port.

Sorry, but I can’t produce one. I have a digital camera, but it only works with Windows 98 and older; it would be too much trouble to dig out, dust off, and set up my old Windows ME box. I could use my phone camera, but then I’d, I believe, get charged $5 for the one photo (I don’t use the service so it would need to be activated).

I probably should have been more descriptive and said that it was a 9‐pin connector with a rounded‐corner trapezoid shape though.

Thanks for the information. Now I know what it is; the port looks to me to be for legacy compatibility and otherwise useless.

Based on the picture in the Wikipedia article showing the icon with one line and two circles, maybe I couldn’t find any information since I was searching for a different description (three lines and two dots); maybe the former is more common or something.

I was mainly curious as to whether or not this had anything to do with eSATA (which I’m clueless about), since I was considering buying a new external hard drive and eSATA is supposed to be fast. As it is, I opted for a IEEE 1394a drive instead, since I know that my computer has connectors compatible with it.
