Pi Pico W (Micropython) - How to enable CTRL+C via UART?

Question

I'd like to remotely control my Pi Pico W using HC-05 or HM-10. It works in general, but in case of infinite loops (like "While" loop), sending CTRL+C via UART does not stop the loop.

It works via USB, but not if I use UART. I use DUPTERM to duplicate REPL on UART0 of my Pico W.

I tried both HC-05, HM-10. Webrepl also uses dupterm and does not allow me to interrup infinite loops using CTRL-C.

I took a quick look at the MicroPython for RP2 source code here:

As a first step, it looks like you will need recompile MicroPython with the MICROPY_HW_ENABLE_UART_REPL option enabled. This setting could go in your board configuration file, for example in ports/rp2/boards/RPI_PICO_W/mpconfigboard.h.
