NetWare Loadable Modules
Novell's NetWare Loadable Modules (NLMs) run on NetWare file servers.
They translate file and directory names and permissions between
NetWare and other systems, such as the UNIX system.
The NUC and NFS NLMs are shipped with SCO Gateway for NetWare. They run on NetWare versions 3 and up. When a NetWare filesystem is mounted from a UNIX system, the loaded NUC and NFS NLMs give the NetWare filesystem UNIX system semantics such as long file names, mixed case letters in filenames, symbolic links and support for owners and groups.
