This has been there forever and I doubt anyone has ever used it.

Andrew Cooper tells me that it needs an L or H suffix so probably
doesn't work.  Recent changes to more conspicuously report command

It needs an L or H suffix to instruct Xen how to mux the console with
the gdb remote protocol based on the high bit on 8-bit clean line.
