Supported types are: * `Q` query input (QEMU -> host). QEMU may emit this frame, so that the host replies with a new input `I` frame (hexvalue of `Q` is ignored) * `R` repeat (host -> QEMU). The host may ask QEMU to repeat the last `D` and `O` frames +* `Y` forwards the GPIO input that QEMU has read to the host (QEMU -> host) for tracking purposes * `Z` output pull up/down GPIO HiZ values (QEMU -> host). 1 means HiZ, 0 means pull up/down values apply.
