new code page list.

set.

Notes:   To set up a new code page list:

  Prepare the IoctlCpPrepRec and call this fn

  Call fn 4403h (send control data) to pass the code-page

character set remapping information to the driver.

  Call fn 440cH 4dH (end cp prepare).

  To reset to the hardware code page:

  Prepare the IoctlCpPrepRec and call this fn

  Immediately call fn 440cH 4dH (end cp prepare) without

sending any control data to the driver.

  To "refresh" the most recently selected code page:

  Prepare the IoctlCpPrepRec, filling all of the ccpIDs fields

with -1 (ffffH) and then call this function.

  Immediately call fn 440cH 4dH (end cp prepare) without

sending any control data to the driver.
