Now that I've got the data sheet in my hand, I think I can answer that.
The maximum clock rate specified for both receiver and transmitter is
2.5 MHz. This gives a data rate of 156250 bit/s.
If you're only interested in the chip as installed in the Archimedes, then
you're stuck with the standard 1.8432 MHz crystal, which gets you
Of course, I've not actually tested any of this.
