How SCO SLIP works
SCO SLIP provides for the use of TCP/IP network
applications (for example, telnet) over serial lines
by providing for the establishment, use, and removal of SLIP
links.
A SLIP link is a serial communication path between two computers
over which data is transferred in the form of serialized IP packets
and over which both machines use SLIP to govern the transmission and
receipt of these packets.
The serial communication path can be a physical cable connecting a
serial port on one computer with a serial port on the other or can be
telephone lines between a pair of modems, a modem at each computer.
