USART2 works but other USARTS don't work. (STM32F446RE) Hello,I am struggling to use multiple USARTs. I tested that USART2 works fine but I cannot get USART1 and USART3 to work. If I can't use multiple USARTs at the same time, I would like to use only USART3. However, USART3 does not work. Do I need to change settings on the Windows to use different USART?I am using STM32F446 nucleo board and using Putty to see serial port on windows.Any help would be very appreciated!Thank youvoid SendInitString(void)

uint8_t Test3[] = "Hello World 33 !!!\r\n"; //Data to send
HAL_UART_Transmit(&huart3,Test3,sizeof(Test3),10);// Sending in normal mode
uint8_t Test2[] = "Hello World 22 !!!\r\n"; //Data to send
HAL_UART_Transmit(&huart2,Test2,sizeof(Test2),10);// Sending in normal mode
uint8_t Test1[] = "Hello World 11 !!!\r\n"; //Data to send
HAL_UART_Transmit(&huart1,Test1,sizeof(Test1),10);// Sending in normal mode
HAL_Delay(1000);
