python - PySerial: How to send Ctrl-C command on the serial line

Question

I'm automating a configuration process for an embedded board. To enter the setup screen I need to send "Ctrl-C" command.

This is NOT to interrupt a process I'm running locally, KeyboardInterrupt will not work. I need to send a value that will be interpreted by the bootloader as Ctrl-C.

What is the value I need to send?

Thank you

IIRC, Ctrl-C is etx. Thus send x03.
