A post a few months back someone posted a small comport.exe file which allows the COM port to be easily manipulated. Unfortunately it only works on the older versions of SOL since the PNP id's have changed. Does anyone have any other methods for setting the COM that can be placed in a machine startup script which runs at the end of Windows Setup on a sysprep image?
I think you could just use a VBscript to handle this. I don't think there's a way to execute code during Windows Mini-setup though, so I think it would have to be configured in your GuiRunOnce section of the sysprep.inf file. That way, it would run the next time someone logged into the system.
