For sending, anything over 4 cycles won't work, so receiving is

You say that a lot about 65C02, but the target in this case IS a //c
after all. :-D I think that in this one case it's a forgivable
sin. But, as you say, if 6 cycles is too slow then the serial port
idea is a non-starter. Oh well, it was worth a shot!
Given that STY,STX,STA are also 4 cycle instructions there's no need
for STZ in this case. All one has to do is ensure
one of the index registers contains a zero in critical part of the
polling loop, which is probably not a big issue.
