Hi all, There excatly are some issues after echo input in driver (https://github.com/apache/nuttx/pull/8691), the default behavior of cu is one of them should be discussed. [https://opengraph.githubassets.com/d9287525ac4414548917840a0f06e871d6208b7ef78597353c79478a6ee0199f/apache/nuttx/pull/8691]<https://github.com/apache/nuttx/pull/8691> drivers/serial: Echo input in driver layer by no1wudi · Pull Request #8691 · apache/nuttx<https://github.com/apache/nuttx/pull/8691> Summary Works with apache/nuttx-apps#1608 Impact nsh Testing nsh and telnet github.com In current master, cu will let local machine handle the echo and CR/LF convertion by default, a major usage of cu (for me) is to connect to a AMP core (running another NuttX ) over uart_rpmsg, now the uart_rpmsg driver disabled its echo to avoid double the input (from the local core and AMP core).
I see some implementation of cu (like BSD) will disable the echo and CR/LF convertion and let remote machine to handle them. I prefer to follow the BSD way, is there any side effect for you? Or do you have any suggetions? BR, Qi
