Used on conjunction with /DEBUGPORT=1394 to specify the IEEE 1394 channel through which kernel debugging communications will flow. This can be any number between 0 and 62 and defaults to 0 if not set. Use this switch together with the /debug switch and the /debugport switch to configure Windows to send debug information over an Institute of Electrical and Electronics Engineers, Inc. (IEEE) 1394 port. To support debugging over a 1394 port, both computers must be running Microsoft Windows XP or later. The 1394 port has a maximum number of 63 independent communications channels that are numbered 0 through 62. Different hardware implementations support a different number of channels across one bus. Windows XP has a limit of four destination computers. However, this limitation is removed in Windows Server 2003. To perform debugging, select a common channel number to use on both the computer that the debugger runs on, which is also known as the host computer, and the computer that you want to debug, which is also known as the destination computer. You can use any number from 1 to 62.
