Hardware Wizard, SIO behavior

Enough is enough. Why is it that XP always treats an unexpected bitstream
on the SERIAL port at boot time as a mouse and loads the MS serial mouse
driver which locks the port?
Other than making sure the the serial device is unplugged/off at boot time,
does anyone know of a way to make the AddNewHardware Wizard ignore the port?

Available switch options for the Windows XP and the Windows Server 2003
Boot.ini files

/fastdetect:comnumber
This switch turns off serial and bus mouse detection in the Ntdetect.com
file for the specified port. Use this switch if you have a component
other than a mouse that is attached to a serial port during the startup
process. For example, type /fastdetect:comnumber, where number is the
number of the serial port. Ports may be separated with commas to turn
off more than one port. If you use /fastdetect, and you do not specify a
communications port, serial mouse detection is turned off on all
communications ports.
 
Well schucky darn. It defaults to /fastdetect without argument. The
problem is that the OS itself scans for changes.
I found a KB on the subject and it is a bit convoluted adjustment.
Especially when the com port is on a USB adaptor.
