In my case, however, I also wanted a "simulated" UART, not a physical one. So I run: socat PTY,link=/dev/ttySIM0 PTY,link=/dev/ttyNX and indeed our software was perfectly capable of communicating with the simulation. Both softwares now run unaltered, both "thinking" of talking to each other through a UART, as in a the real-world case. Perfect! Needless to say that this is a killer feature of NuttX. It opens up a huge array of possibilities for testing (especially automated / CI), and development without the strict need of hardware. Thank you all!
