UART between Jetson Nano and PC

Hi, I connect two UART pins on J41 of my Jetson Nano board, with my serial to usb cable, to my PC. It is ttyTHS1 under /dev/ , am I right?
When I launched serial utility on PC(win 10), try to open the COM port it detected with the setting (115200,8bit), it failed to open the port. Do I need to do something on Jetson Nano so that I can open the port by serial utility on PC?

UART on the J41, it is a general purpose UART not a debug console.
And cause of 3.3V TTL, you may use a TTL to USB serial cable.

Then you can use UART comm. via J41.

Yes. I do use a TTL serial to USB cable.
What I want to know is, if I want to let my PC communiate with Jetson Nano via this UART, by my TTL serial to USB cable, using Serial Utility tool on my PC, do I need to something else? For example, to open this port on Jetson Nano?

@bobokang_2003,
For me, nothing else.
Only minicom needs for me at my ubuntu desktop.

Jetson Nano side, there is a simple UART demo:
