INT 2F - DR DOS 5.0+ NLSFUNC - PREPARE CODE PAGE
AX = 14FFh
BX = code page (see #01757 at INT 21/AX=6602h)
Return: AX = ???
ZF set if AX=0000h
Notes: DR DOS 5.0 NLSFUNC returns CF set and AX=0001h if AL was not 00h, FEh,
or FFh on entry.
passes codepage preparation request to each character device supporting
the generic IOCTL call
BUG: DR DOS 5.0 NLSFUNC 3.00 - Novell DOS 7 NLSFUNC 3.03, and OpenDOS 7.01 -
DR-OpenDOS 7.02 NLSFUNC 3.02 requires DF cleared on entry, otherwise
the system may crash. However, since this function is called only by
the BDOS, the problem never actually occurs. DR-DOS 7.02/7.03
NLSFUNC 4.00+ always clears DF by itself.
