You can do 57,600 and even 115k on an Apple IIe with a Super Serial Card and a Turbo ASB board. Ron Higgins is still selling the Turbo ASB card (which is just a piggyback for the SSC). There is also a software hack that will allow 115k only on the SSC, but this requires rewriting code. The Turbo ASB fixes a timing bug in the older 6551 ACIA.
To be fair, the only "code it requires rewriting" is the code that initializes the 6551 for transmission speed--sort of a minimal change, I'd say. -michael New, faster SUDOKU v2.0 solver for Apple II's!
