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. -- ----------------------------------------------------------------------------- Matt Deatherage, Apple Computer, Inc. | "The opinions expressed in this tome Send PERSONAL mail ONLY (please) to: | should not be construed to imply that Amer.
