SCI does not have a fifo, it is necessary to send and receive

But, qemu's chardev backend does not have a buffer,

By buffering the received data with the FIFO, continuous
received data can be received.
Hi!
If you describe it like this, it sounds like you're now emulating a buffer
that is not there with real hardware? Is that really what you want here,
i.e. wouldn't this hide problems with the real hardware that are mitigated
in QEMU with this buffer?
Anyway, please use scripts/get_maintainer.pl to get a list of people who
should be put on CC:, otherwise your patches might get lost in the high
traffic of the mailing list.
