i guess you can do about anything your pc and your rs-232 driver can do, up
to 1.25Mbps, according to the data sheet (i didn't try that one, though :)

the limiting factors would probably be the driver you use (they have a max.
speed specified), of course the max speed of your pc (usually 115.2kbps),
and the distance, noise and type of cable in your application. with the
right driver (eg. max232, spec'd up to 120kbps) in a normal home
environment 115.2kbps shouldn't be a problem. in any case you need to
choose a crystal that allows you to generate the bit rate you want.
