lukegluke commented on issue #176: Fix echo NULL character correctly URL: https://github.com/apache/incubator-nuttx-apps/pull/176#issuecomment-614272725 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 ~.
