Many UARTs won't run more than 115K, so that is a fair bet ;-)

But many more do.

Gazillions of UARTS in microcontrollers will run way faster than that.
I've done 1mbit/s in a PIC, between two devices on a PCB.

We used to run the archive tape drives on System X at 880k over 150m of
cable.
We invented a new tape protocol just for the job as we hated the stupid
ascii interface Tandberg had chucked together.
That was in the '80s
