Is there a way to use the full UART IDF functionality (UART-ISR) in Arduino.
As is possible e.g. in the Arduino Pico core, with full SDK functionality

What functionality are you missing? HardwareSerial uses the IDF, but hides a lot of the complexity. You can also get direct access to IDF functions by compiling "Arduino as IDF component", but that's difficult to build correctly.

P1: Rx- and Tx-Interrupt
See Serial.onReceive()
#6134
P2: RTS and CTS
You are correct. I don't see that option in this repository.

thanks for info about Serial.onReceive()
Is there an option Serial.onEndTx()
I need an Int "EndOfTx" after each char who was transmitted.
Have you an idea what we can do to realise RTS/CTS

// negative Pin value will keep it unmodified
void HardwareSerial::setPins(int8_t rxPin, int8_t txPin, int8_t ctsPin, int8_t rtsPin)
{
if(_uart == NULL) {
log_e("setPins() shall be called after begin() - nothing done");
return;
}
uartSetPins(_uart, rxPin, txPin, ctsPin, rtsPin);
}
I haven't used RTS/CTS.

HardwareSerial::setHwFlowCtrlMode()

I don't see an interrupt for TX. You could: 1) set TX buffer size to 1. 2) Use void HardwareSerial::flush(bool txOnly) 3) Use size_t HardwareSerial::write(uint8_t c) to write one character at a time. Sounds inefficient.

Thanks for the HardwareSerial::setHwFlowCtrlMode() infos.
Tx-IRQ is really needed!
