Exactly - 11 bit-times per dataword.
But the problem is already identified and was not on the FreeBSD
side as I wrote in another mail.
Now I'm worried with the sending timing - maybe I should switch to
uftdi based serials, because they have large fifos and also have
a transmitter enable output for half-duplex operation.
Currently I handle transmitter enabling via RTS line from userland,
which leaves a potential for not having the transmitter disabled when
the accessed slave answers.
