* If you compiled Bochs with the --enable-e9-hack, then any character
* printed to the 0xE9 I/O port is printed to the xterm that is
* running Bochs. This may appear to be a detail, but in fact, this
* functionnality is *VERY* precious for debugging purposes. This
* """driver""" handles this feature.
