Shifting Caption Text Up using the Parallel Remote Control

When this GPI is held low, screen position codes (called PACs) in the
caption data will be translated so that captions normally appearing on rows
12 through 15 will now appear on rows 1 through 4. This is intended to
provide compliance with FCC rules, which state that caption text may not
overlap emergency information that often appears at the bottom of the
screen.
Decoded captions may not shift up immediately when this GPI is enabled,
only when a new PAC is transmitted. Some real-time captioning software
packages using roll-up style captions do not insert PACs at all, so these
captions will not be shifted up even when this GPI is enabled.
