Code:

Serial.println("UDP OK");

Now I want to receive a char from a terminal

Code:

void UART_Get()
{
     char chr;
    if (Serial.available() > 0)
    {
        chr = Serial.read();

        //for debug
        Serial.print(chr);
    }
}

and I put it in a loop

Code:

void loop()
{
     UART_Get();
}

But I get nothing.
I test the RX pin with a scope and I see incoming signals on the pin.
What can be wrong?
