    Hi,

    I want to use USB in virtual com port mode. Basically I want to make a modem on one of the STM32 serial ports accessible from a Windows PC connected to the STM via USB. In the USB examples I don't see anything that would support the control of handshaking lines such as DTR or DCD. Th PC will try to use all the handshaking lines e.g. DTR for call hang up. I don't think the ST USB virtual com port driver supports this and the C code does not seem to either.

    Would it be difficult to add support for this to the Windows driver and to the STM32 code? Any thoughts?

    Thanks

    Trevor
