Hi All,

i'm using STM32F407 in USB CDC mode,
i'm having issue when i'm sending bytes from STM to PC,
client application on PC is minicom,
issue is when i close minicom and STM runs into "frozen" state until i open minicom again, and after opening minicom everything continues in normal running state,

is there a way how to detect that client application is closed ? so i will stop sending bytes to PC,
i found that STM got Ctrl call with Cmd 0x22 when i close minicom and same code 0x22 when i open minicom :-(

Thanks for all replies,
Kind regards,
