- That's not a limitation of the Zilog SCC; the problem is the tty
- driver only using 4 bits to represent possible baud rates under
- SunOS. Not to mention Sun's non-implementation of hardware flow
- control (that has been hashed over many times in this group).
- If the TIOCSET* ioctls were finally obsoleted, and the baud
- rate could specified as an integer, the SCC could be programmed
- for much faster rates.
