I got the following link. > > http://www.ibm.com/developerworks/aix/library/au-debugfreebsd.html#list1 This article is inaccurate in a number of points, notably building the kernel. I'd recommend that you read the document at http://www.lemis.com/grog/Papers/Debug-tutorial/, which also gives you much more information about the debugging process. > My problem is my developing and target system does not have DS25 > female port.

That should work just as well. There's nothing special about the link. But if you have any alternatives, don't use an async serial cable for kernel debugging. It's glacially slow, and people have had all sorts of problems with it in the course of time. Firewire is much better, and you may even find that the hardware is cheaper.
