hello,
I have a ciruit that gives me a signal through 9 pin serial cable. The bad news is that I don't have 9 pin serial port on my laptop I have 15 pin instead. Is there a cable that have 9 pin from one side and 15 pin from the other side? or is there any solution for my problem?
thanks in advance

You can buy a simple 9 pin adapter at most electronic supply stores, such as Radio Shack, Best Buy and Amazon Here are other suggestions

I think that u misunderstood me, I have a 9 pin adapter connected to the ciruit. on my laptop I only have 15 pin port . Is there a cable that supports 9 to 15?

Yes, there are serial cables with 9 pin on one side and 15 on the other. You can also attach adapters at the ends of the cable to convert them between male/female and 9/15 pin.
