'baud' and 'bits per second' aren't the same thing.

'baud' means 'number of line state changes per second', but modems
faster than 2400 baud use multiple states, each one representing
different combinations of bits.

For example , if we have 4 states: 00, 01, 10 and 11, at 2400 baud we
will get 4800 bits/second.

Telstra's lines are rated at 2400 baud, but that doesn't mean we can't
get 33600 bps out of them :)
