Null Modem Cable An RS-232 cable used to connect two personal computers
together in close proximity for file transfer. It attaches to
the serial ports of both machines and simulates what would
occur naturally if modems and the phone system were
used. It crosses the sending wire with the receiving wire.
NVM Non-Volatile Memory.

any network information or request sent by any other ODI-
compatible protocol into something a NetWare client can
understand and process.
Open System Authentication Open System authentication is a null authentication
