RS-232 — EIA standard specifying the physical layer interface used to connect a device to

communications media.

Serialization Frames — Frames sent out by servers under IPX to check whether illegal copies of

NetWare are in use on the network.

Service Advertising Protocol (SAP) — Protocol used by IPX for broadcasting information

about services available on the network, such as ﬁle servers, CD-ROM drives and modem pools.

SNAP — Sub-Network Access Protocol. An Ethernet or Token Ring frame type that adds
