问题描述：
使用IWR6843ISK 开发板，下载C:\ti\mmwave_industrial_toolbox_4_10_1\labs\Vital_Signs\68xx_vital_signs\prebuilt_binaries\vital_signs_demo_68xx.bin, 成功下载，切换S1到功能模式，如图。
IWR6843ISK与pc连接，能正常检测到设备：
打开GUI 工具C:\ti\mmwave_industrial_toolbox_4_10_1\labs\Vital_Signs\68xx_vital_signs\gui\gui_exe\VitalSignsRadar_Demo.exe，自动检测Com Port，cmd line显示打开失败：
QT version = 5.9.1
QMetaObject::connectSlotsByName: No matching signal for on_buttonBox_accepted()
Serial Port Found
Data Port Number is "COM7"
User Port Number is "COM7"
Data port succesfully Open
User port did not Open
QIODevice::write (QSerialPort): device not open
上述log可以看到User Port Num和Data Port Num选择的都是COM7，实际应该是COM8，即使手动修改User ComData Port Number 为COM8，点击Refresh，也没有作用，手动点击Settings，进去后也无法输入COMx端口号。请问可能是哪里错了？感谢支持！
