I think that 115200 bps is doable. At this rate, you need to send a bit
every 10.32 cycles. If you do 11 cycles for the start bit, 10 for each data
bit, and 11 for the stop bit, that's only one cycle off - it might work.
Also, if you unrolled the loop in the send subroutine, 230400 might be
possible. I think the cycles will work out, but the issue here is space in
the 128 bytes, which is pretty full already.
I think 115200 is a better goal nonetheless since 230400 is on the fast side
for serial ports anyway. I'll give it a shot.
