Detailed Description

Definitions and classes for USB CDC class requests (mostly for ACM).

CDCLineCoding

1. Initialize a CDCLineCoding instance using CDCLineCoding_Initialize.
2. Send a CDCLineCoding object to the host in response to a GetLineCoding request.
3. Receive a CDCLineCoding object from the host after a SetLineCoding request.

Definition in file CDCRequests.h.
