Some of the (mostly common now) newer chips that control the serial port can go that high (115 to 230.4 I think might be MIDI (digital musical instrument) speeds)... 33.6KB, 57.6kb etc. is usually in reference to modem communication speeds, which also use the serial connector but have to convert the digital data to analog sounds and back again over the phone line, this obviously slows things down quite a bit, but in your case, you are talking about a "direct connection" between the Visor and the computer, so you can go higher as there is no "modem" involved between your Visor and the serial port on your computer.
Ironically the "wire" between your (external) modem and your PC might actually be operating at 115kb (or higher), however, because of the digital to analog , analog to digital conversion limitations, because of this bottle neck, you won't see the overall performance go beyond 56kbs, it just means that the computer can "talk to" the modem quicker (and vice versa). Internal modems work somewhat the same way, but the "wire" I am talking about is "built in" so it's harder to visualize.
