Enable debug interface on Serail1

Hello together,

I would like to enable the debug interface. I have a ftdi USB to TTL adapter connected to rx and tx and the adapter connected to a usb port.

After that I have executed all the steps described under "Enable debug interface on Serail1"

How do I get the log file now? If I initialize Serial1 and open the monitor at the appropriate com port nothing happens.

My code looks like this:
```
void setup() {
Serial.begin(9600); // initialize serial communication
Serial1.begin(115200);
log_init();
}
```

Start with the setup() entry point shown in the report, especially Serial1.begin(115200) and log_init(), and review the documented "Enable debug interface on Serail1" steps. Verify the RX/TX wiring, selected COM port, and monitor baud rate; done means the expected log output appears on Serial1.
