USB CDC parity error support for virtual serial port

I use the CCS usb_cdc.h library in a virtual serial port device and need to report parity errors. I believe parity errors are reported using CDC SERIAL_STATE notifications (notification code 20). SERIAL_STATE also reports DCD, DSR, break, RI, frame error, and overrun error.

Does anyone have an example of how to access these bits in the SERIAL_STATE service? How do I report parity errors to the USB port?

Thanks.

Did you e-mail me about this? If so I e-mailed you an update of the code that has an API for sending SERIAL_STATE to the host.

For reference, the next version of the compiler (4.126?) should have an update to the USB code. See ex_usb_serial.c for an example of this API.
