I rethink my question again and this depends on HW configuration also, so
can't be handled at driver level generically.

Hello Alan,
Thank you. I will try to port SW RS485 to ESP32-S3, but from my experience
in the past with RS485 I have a question: how TX echo is filtered out from
RX stream when SW RS485 is used? Or that should be done at the application
layer?
Best regards,
Petro

Hi Petro,
The current RS485 implementation used on ESP32 is not using internal
RS485 controller of ESP32, it is implemented by "software". So you can
use it connecting a RS485 transceiver to UART port and using the right
DIR pin controller by RS485 driver.
It is possible to use the internal IP RS
Hi,
I'm currently trying to enable RS485 support for ESP32-S3. I see that there
is some support of RS485 mode in ESP32 and it seems to be straight forward
to port it to ESP32-S3 however I see that currently ESP32-S3 lowputc has
next lines
modifyreg32(UART_RS485_CONF_REG(priv->id), UART_RS485_EN_M
