Hi All,

I am implementing the CDC device in the STM32F4 series (using the Discovery board and the STM3240G-Eval board).
I made it work but I noticed (at least on Windows XP) that the commands sent to change RTS/DTR and BREAK do not work. Is it a problem with the Windows drivers (not implemented) ?
The calls arrive on VCP_Ctrl routine but Buf is always null (unless the command is to set or get the LINE_CODING. I would like to have a complete implementation (because I need the break signal and DTR/RTS.

Thank you very much.
