【求助】串口的波特率怎么改到新建会话连接界面，数据格式怎么默认设置text格式

This issue has no description.

The issue provides no body, files, tests, or implementation entry points. Start by locating the serial-port settings and the new-session connection interface, then determine how baud rate and data format defaults are represented. Done means the requested serial settings can be configured or defaulted in that interface, with a test or reproducible verification.
