 capture, you will need a real COM port on the motherboard in order to
 connect to a second computer. Using a USB adapter requires a driver that
 uses the USB stack to communicate with the device. The USB stack cannot
 actually run while in KDL (because KDL halts all execution of the OS,
 drivers, etc.), which is also basically why you're having issues with your

 I now have a serial port on my computer (direct COM port extension)

 keyboard attached to that - if it does not, there are some options for
 having the BIOS take control back of the keyboard, but I think that only
 works when it is connected to a USB1.1 hub or something?

 Unfortunately, no PS2 port. i hope that the serial debug will be
 successful. Anyway do you know how to set it ? Is it part of the
