- Yes you can... But you'll have to hack the kernel to do it.
- You can even make it go 76800 bps.

- Check out ftp.lysator.liu.se:pub/sun/misc-info/Sun76800BaudSerial.txt for
- more information.

- But I agree, Sun could have choosen to use the newer Z85230 (I think that
- was the name of the new version of the old Z8530) chip. It has receive
- and transmit FIFOs making it possible to reduce the number of interrupts
- needed (with a little clever programming) while still being backwards
- compatible.
