The ESP32-C6 datasheet shows that the UART1 can be configured to use any GPIO pins, the UART driver that comes with esp-idf allows to assert the DTR pin by using the function uart_set_dtr() but there is nowhere in the driver where you can specify the pin to be used for the DTR signal, only TX, RX, RTS and CTS pins can be set.
Does anyone have an idea how to set the pin to be used for the UART1 DTR signal?
