+
+ !!!Purpose
+
+ Line coding structure used for by the CDC GetLineCoding and SetLineCoding
+ requests.
+
+ !!!Usage
+
+ -# Initialize a CDCLineCoding instance using CDCLineCoding_Initialize.
+ -# Send a CDCLineCoding object to the host in response to a GetLineCoding
+ request.
+ -# Receive a CDCLineCoding object from the host after a SetLineCoding
+ request.
