The PK-232 provides RTTY operation in the Baudot/Murray code at 45, 50, 57, 75 and 100
bauds, corresponding to approximately 60, 66, 75, 100 and 132 words per minute (WPM).

The number you enter becomes the new data rate and replaces the value previously
stored in the program.
You can also change the baud rate one step up or down one step at a time by typing
