That is the frequency, the controller runs with in Hz. which
clock source is used and the possible clock modification depend
on the fuse settings. http://palmavr.sf.net/cgi-bin/fc.cgi
may be useful here.

Keep in mind, that the usart interface has a 2x setting that doubles
the baudrate, but this is unused in the default sources.

btw: The template directory is a much better starting point since the
relevant files are better documented.

If you use the default sources, connect with usart0.
