If you don't, you only get the clock crystal frequency, and baud rates from there down from cutting the frequency in half for each one. You *can* change out the clock crystal if you are into hardware hacking; before there were MIDI cards, a lot of MIDI hackers changed out the crystal to get MIDI speed, and then used a converter to drive current loop (MIDI is a current loop interface).
