Class UART methods in ESP32

[TomLinz]

With PyBoard, I use MicroPython class UART and its methods UART.any(), UART.readinto()
and UART.write(). I want to port my code to the ESP32-PICO-D4 module, but wonder if
these three MicroPython methods are implemented in ESP32?
Examples I have found mention only methods UART.write() and UART.read().

IYou can list all implemented elements of the UART class by:

from machine import UART
print(dir(UART))

Thanks Robert, this was a nice answer! Seems the methods I need are implemented. And I learned a valuable new trick :-)

Further question related to ESP32 UART.init() method. Tried to read back settings of the UART in the same manner. However:

dir(UART.init)
['class']

dir(UART.init())
Traceback (most recent call last):
File "", line 1, in
TypeError: function missing 1 required positional arguments

dir(UART.init(baudrate))
Traceback (most recent call last):
File "", line 1, in
NameError: name 'baudrate' isn't defined

Is there any other way to read back default settings of UART.init() method, such as txbuf size?

You can do this (as shown by the following example):

MPY: soft reboot
MicroPython v1.20.0-487-g00930b213-dirty on 2023-09-24; ESP32S3-WROOM-1 N16R8 UART (KAKI5) with ESP32-S3
>>> from machine import UART
>>> urt1 = UART(1)
>>> print(urt1)
UART(1, baudrate=115211, bits=8, parity=None, stop=1, tx=10, rx=9, rts=-1, cts=-1, txbuf=256, rxbuf=256, timeout=0, timeout_char=0)

Thanks alot, this works fine for me!
