### Function 116h - Flags

Flags

Defined as follows:

    Bit 0 indicates whether the physical video

          buffer needs to be updated.

          OFF = The physical video buffer must not be

                updated.

          ON  = The physical video buffer must be updated.

    Bit 1 indicates whether the logical video buffer

          needs to be updated.

          OFF = The logical video buffer can optionally be

                updated.

          ON  = The logical video buffer must be updated.

    Bit 2 indicates whether ANSI is active.

          OFF = ANSI is not active.  Escape sequences should

                be considered as text data.

          ON  = ANSI is active.  Escape sequences must be

                handled locally or passed to the default

                routine in BVS through device chaining.

    Bit 3 indicates whether Ctrl_PrtSc is active.

          OFF = Ctrl_PrtSc is not active.

          ON  = Ctrl_PrtSc is active.  Characters need to

                be echoed to the printer locally or by the

                default routine in BVS through device chaining.

    Bits 4-15 are reserved and must be OFF.
