The SPI (synchronous peripheral interface) does not do normal RS-232
(aka "asynchronous serial") in hardware. you must write an assembly
language driver to do the timing.
at some point in january i plan to release a 1200 baud output driver.
if someone beats me to it that is fine.

| Perhaps I have just overlooked this in the documentation for the HB and IC. Is there an easy way to control the chip selects Y*? Are they memory mapped or harder to get to than that? Thanks for the info: patrick (28 years ago, 21-Dec-96, to lugnet.robotics.handyboard)
