You need some "magic baud" crystals! I'm partial to 11.0592 because it fits nicely under chips rated for 12MHz without wasting much, and a lot of parts rated for 10 will happily overclock there quite stably.

- Teknoman117 6y agoYup! I have some on hand, but the DUART only takes a single clock line and I didn't have the parts for to build the crystal driver. This particular 8051 has a built in one, but no oscillator out. Was contemplating using one of its timers. I didn't even realize the AVR supported a clock out until I bumped into it in the data sheet. Maddeningly it's not broken out on the Arduno Mega =P.
