              INT 21,63 - Get Lead Byte Table  (MSDOS 2.25 only)

       See below for information on the Asian INT 21,63 specifications

       AH = 63h
       AL = 00  get address of system lead byte table
          = 01  set or clear interim console flag
          = 02  get value of interim console flag
       DL = 00  clear interim console flag (when AL=01)
          = 01  set interim console flag (when AL=01)

       on return
       AX = error code if CF set
       DS:SI = far pointer to lead byte table (AL=00)
       DL = value of interim console flag (AL=02)

       - available only in MSDOS 2.25
       - provides multiple byte character support
       - function 00, returns the address of system table containing
         legal lead byte ranges
       - function 01 & 02 set and get the interim console flag which
         determines whether interim bytes are returned on some console
         functions
       - all registers except CS:IP and SS:SP may be destroyed


              INT 21,63 - Get Lead Byte Table  (Asian DOS 3.2+)

       AH = 63h
       AL = 00  get address of Double Byte Character Set (DBCS) lead table
          = 01  set Hongeul (Korean) input mode
          = 02  get Hongeul (Korean) input mode
       DL = new keyboard input mode
          = 00  return completely formed characters only
          = 01  return partially formed characters also


       on return
       AL = 00 on success
          = FF if function not supported
       DS:SI = pointer to DBCS table  (function 00)
       DL = current keyboard input mode (function 02)
          = 00  only completely formed characters are accepted
          = 01  partially formed characters are accepted


       - available only in Asian MSDOS 3.2+
       - provides Asian multiple byte character support
       - all registers except CS:IP and SS:SP may be destroyed
       - DOS 4.0 returns an empty list
