Requires that a Save Current Settings packet (command scs) be sent immediately after a Set VCP Feature packet (command setvcp) to actually set the value.

Never sets the unsupported feature bit in a VCP Feature Reply packet (command getvcp). The capabilities command must be checked to determine if a feature is supported.
