Don't be putting words in my mouth.  I know what I said, even if I'm not
looking at it (at least, I know what it's supposed to say).

Apple II Misc. TN #14 does not say doing single-character I/O through the
firmware is not possible at speeds greater than 2400 bps.  It does say that
single character I/O through *GS/OS Generated Firmware Drivers* (and every
word of that phrase is key) is not practical.

Big difference.
