(...) Whoa! Somebody slap me if I'm wrong, but I thought the HB was incapable of using speeds far above 9600. If it's not, then I've been wasting time. The only thing I could think of doing is building a data buffer, but it seems like that would (...) (25 years ago, 16-Jul-99, to lugnet.robotics.handyboard)

(...) You can communicate at higher baud rates (19200 or 38400) on an 8MHz 68HC11 if you disable SCI and use software "bit-bashing" routines. I have enclosed examples of such routines in sw_baud.s11 file. Setting the BIT_TIME to 52 or 104 allows you (...) (25 years ago, 25-Jul-99, to lugnet.robotics.handyboard)
