Implementation Reference
- src/uart_mcp/tools/terminal.py:12-37 (handler)The core handler function for the 'create_session' tool. It invokes the terminal manager to create a session on the specified serial port with given configuration and returns the session info as a dict.
def create_session( port: str, line_ending: str = "CRLF", local_echo: bool = DEFAULT_LOCAL_ECHO, buffer_size: int = DEFAULT_BUFFER_SIZE, ) -> dict[str, Any]: """在已打开串口上创建终端会话 Args: port: 串口路径 line_ending: 换行符类型（CR/LF/CRLF） local_echo: 是否本地回显 buffer_size: 输出缓冲区大小 Returns: 会话信息 """ manager = get_terminal_manager() session_info = manager.create_session( port=port, line_ending=line_ending, local_echo=local_echo, buffer_size=buffer_size, ) return session_info.to_dict() - Input schema definition for the 'create_session' tool, including parameters like port (required), line_ending, local_echo, and buffer_size.
