How can I transmit a UART message using a SMT32G474 B-G474E-DPOW1

I am not new to working with STM32 MCUs but this is a one-of-one.

I have checked the baud rate to 115200 with 8E1, the serial com port driver is showing up on my computer and when I measure the USART-TX pin using an oscilloscope it is showing a signal. I am not getting any errors.

This said however, there is nothing showing up on my teraterm terminal or termite terminal, I am open to suggestions, been trying to fix this all day :)

Why not 115200 8 N 1 ?

ST-Link VCOM is not a complete implementation of CDC ACM. It may not support some features/options.

G474 have 3 USART and variants for pin for every signal. Only one is connected to VCOM on debuger bridge.

You dont explain what you scope and ...
