   Hi @xiaoxiang781216 
   
   Sorry for late reply, for some reason github do not inform me about discussion!
   I totally agree that writing back what cu receive from serial is always a good action, and I was surprised why it is not default.
   But -f option is **not only** to force write back null char! @Ouss4 is right with -f option cu doesn't stop on escape characters ~.
