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 #01680)
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.. From the DR DOS "Panther" BETA COMMAND.COM (1992/06/22) up to some of the Novell DOS 7 COMMAND.COM updates (1994/09/12), the shell made calls to INT 2F/AX=11F0h to attempt "remote server COPYing". However, this was removed from later releases of the shell because it stopped Performance Technologies' PowerLAN 3.1 working. (A successor of the DR-DOS 7.03 COMMAND.COM may possibly reintroduce this remote copy feature. Probably it would then try both INT 2F/AX=1127h and INT 2F/AX=11F0h.)
