Int 2F Fn 1127  - Netware 4.0 - Remote File Copy                           [N]

   AX = 1127h
   BX = 4E57h ('NW') (signature identifying this as a NetWare call)
   SI = source file handle
   DI = destination file handle
   DX:CX = number of bytes to copy, starting at current file position

Return: CF clear if successful
   CF set on error
       AX = error code (05h,06h,0Bh,11h,3Bh) (see #1366)
   DX:CX = number of bytes successfully copied (file position updated)

Notes: this is the only call which may be made directly to the NetWare
     redirector from an application
   COMMAND.COM's COPY and DOS's XCOPY reportedly call INT 21/AX=1127h in
     order to speed up copies between files on the same network server;
     if error code 11h (not same device) is returned, the copy is
     performed in the usual manner.  However, no such calls appear to
     be present in MS-DOS 6.22.
