- [patch]

- Just a small note. This patch is not needed to set the speed to
- 56000/57600 or 115200 bps. The serial driver works fine without the
- patch if the only two speeds you want above 38400 are those two. The
- patch may be required to install a custom speed though. Refer to Ted's
- post of yesterday.
