### fastbaud Alternate Baud Rate Mapping

AccelePort adapters support baud rates in excess of the maximum baud rate supported by Unix. To enable the use of these fast baud rates, a ditty parameter, fastbaud, has been provided.

The command ditty fastbaud alters the baud rate tables according to the table on the following page.

ditty -fastbaud cancels alternate baud rate mapping.

#### Example:

If fastbaud is active for a port on an Xr 920 adapter, setting the baud rate to 4800 results in an actual baud rate of 921600.
