Dear Achim.

If they do some kernel-mode debugging, for sure. It raises the
connection speed up to 45x compared to the virtual COM port plus
allows debugging drivers directly from Visual Studio at a reasonable
speed using VisualDDK.

OK. I am not sure whether I can instantly make a complete patch adding
the functionality to the source tree, as my knowledge of VirtualBox
internals is limited to registering I/O port handlers. I would prefer
publishing the source code for a module implementing the PPDMDEVREGCB
interface and specifying, what parameter (port number) needs to be
read from the per-machine configuration. If it is possible for you (or
any other developer) to integrate the module into the source tree, it
would be much faster than me researching how the integration & global
configuration works. If this is not possible, please provide me with a
link to some sort of a HOWTO document on adding custom devices into
the tree.
