Hi, all: I have a PR (drivers/pty: Echo input by default by no1wudi ・ Pull Request #8846 ・ apache/nuttx (github.com)<https://github.com/apache/nuttx/pull/8846>) which align the pty behavior to linux/bsd,
Also fix the ECHO issue with microadb after #8691<https://github.com/apache/nuttx/pull/8691> adb shell will echo normally with this patch. Telnet and adb are tested, for other usage, maybe should disable these behavior munally by termios as other OS. BR
