How to read/write from Jtag serial port

[mishagreen]

I have an EPS32 app that uses uart_write_bytes and uart_read_bytes. I want to port this to an ESP32-C3. Can I use the JTAG serial port with uart_read/write_bytes? If so, which UART_NUM do I use? If not, is there another way of writing/reading to the JTAG serial port?

I guess you mean USB jtag/serial controller and if this is the case you cannot use uart functions.
