What changed

新特性
  • UDP 通信模式: 新增 UDP Server 与 UDP Client 配置页面和完整收发支持，并补充连接控制器、设置面板及串口窗口测试
修复与完善
  • 接收文本净化: 文本接收模式会过滤 ANSI 转义序列，避免终端控制码污染显示内容
  • 连接配置收敛: 移除重复的内联连接编辑器，由 SettingsPanel 统一管理串口、TCP 与 UDP 配置
  • 串口占位项识别: 将“无可用串口”占位项正确识别为串口类型，避免连接模式误判
Features
  • UDP communication modes: Added UDP Server and UDP Client configuration pages with complete send/receive support, plus coverage for the connection controller, settings panel, and serial port widget
Fixes & Enhancements
  • Received text sanitization: Text receive mode now filters ANSI escape sequences so terminal control codes do not pollute displayed content
  • Consolidated connection settings: Removed the duplicate inline connection editor; SettingsPanel is now the single configuration source for serial, TCP, and UDP connections
  • Serial placeholder detection: The no-port placeholder is now classified as a serial entry, preventing connection-mode misclassification
