I assume it's similar to a serial port. As I stated in another newsgroup, the mouse port is identical to another keyboard port. If you attached another keyboard to the port and knew enough to replace the appropriate vectors, you would have a dual keyboard machine. (IBM has hospital offerrings where the second port uses a light pen that behaves like a keyboard.) On the matter of "how fast the serial port," that will depend on your machine and your interrupt handler. The faster the machine, the quicker it can process each incoming byte. Thus, the same machine's serial port is likely to work at a faster speed if you are able to replace its innards with the Power Platform.
