+Redirect the debug console to host device @var{dev} (same devices as the
+serial port).  The debug console is an I/O port which is typically port
+0xe9; writing to that I/O port sends output to this device.
+The default device is @code{vc} in graphical mode and @code{stdio} in
+non graphical mode.
