It would be fun to test however, and I think it wouldn’t be too hard to hit at least 115,200 bits per second coming in over serial and being pushed out over the parallel port with the current setup.

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Ardui… ...
