Using the Ethernet Interface
This chapter provides an overview of the Ethernet local area network
capability of the control coprocessor. It provides information on how to:
connect to the network using a transceiver (Medium Access Unit)
configure the Ethernet port
send/receive communication using the FTP and TELNET utilities
prepare client/server applications using socket-library calls in your
C program
send/receive communication using Allen-Bradley’s INTERCHANGE
t
software and the INTERD daemon
use the SNMPD daemon

Ethernet is a local area network that provides communication between
various computers (hosts) at 10 Mbps. The communication can be via
thick- or thin-wire coaxial cable. The control coprocessor communicates
using the OS-9/Internet software package.
OS-9/Internet provides communication between OS-9 and other Internet
systems using Transmission Control Protocol/Internet Protocol (TCP/IP).
OS-9 Internet C library functions provide a programming interface nearly
identical to the BSD UNIX “socket” interprocess communication facilities.
