Support for Higher Baud Rates?

[digamesystems]

Hello!
This is probably a rookie question in this forum... :)
Looking at Espressif's documentation, it appears that the ESP32 is capable of higher baud rates than those supported by the Arduino Serial class. (max=460800 baud) -- Apparently, in UART mode it's supposed to be capable of up to 5MBS. Has anyone explored this from the Arduino side? I realize over the USB interface this may be impractical but having the ESP talk to another device at high speed, do some processing and report back at a lower speed over UART would be great for a project I'm working on.
Thanks for the great work!
Regards,
John

UART should work at high baud rate. I have tested it using Serial Monitor with 2Mbps.
