## Summary Both the UART and PTY serial drivers previously assumed all VT100/ANSI escape sequences were fixed 3-byte CSI sequences, causing longer CSI and SS3 key sequences (such as Home, End, Delete, and modified keys) to leak stray characters into the terminal when local echo was enabled. This patch replaces the fixed-length logic with a state machine that correctly recognizes and suppresses escape sequences of any length, while preserving the data delivered to applications. The change only affects local echo behavior, is fully backward compatible, and has been validated with both interactive NSH sessions and automated PTY tests. Assisted-by: Claude Code ## Impact Users will be able to use keys arrows, Home, End, etc to edit the nsh> command line (patch to nuttx-apps will come) ## Testing <img width="1250" height="195" alt="image" src="https://github.com/user-attachments/assets/4d4d5a3f-5d61-46c8-8239-fe2aac6cba5f"; /> -- This is an automated message from the Apache Git Service.
