to the name of the IEEE-488 device. The serial line will be used for the
login, and the IEEE-488 bus will be used for graphics. Environment
variables are described in csh (1) and sh (1).
— To establish communication over an Ethernet, enter the name of the
host.
For Ethernet communication, the host must have network support
software installed. For XNS communication, the host must be running
the xnsd (1M) daemon. For TCP/IP communication, the host must be
running the telnetd (1C) daemon. If you do not know the name of a U
nix
host, enter the hostname (1) command on a terminal that is already logged
onto such a host.
The IRIS establishes a connection with the host, which should display its
usual login prompt.
• An unconfigured IRIS 3010 with TCP/IP communication capabilities
prompts for the Internet addresses of the IRIS and the host:
Enter IRIS IP address:
Enter host IP address:
Only Internet addresses consisting of four numbers separated by periods
( n.n.n.n ) are accepted.
To convert a two-field Internet address to the correct format, insert two
fields of zeros in the middle of the address. For example, if the
representation of a host name in the /etc/hosts table on a 4.2BSD U
nix
system is “42.2”, enter the address as “42.0.0.2”.
The IRIS establishes a connection with the host, which should display its
usual login prompt.
Once communication with the TCP/IP host has been established, you can
copy an Internet host table onto the terminal’s hard disk (see Section 5.3.4).
You can then connect to an TCP/IP host by simply entering the name of the
host when prompted. See the documentation that accompanies the
communications software.
5.2.2 Issuing Commands to the Terminal Emulator
After a connection with the host has been established, the terminal emulator
program recognizes some local commands, which are stripped from the data
stream and processed locally instead of being transmitted to the host. The
commands begin with ~.
To issue a command to the terminal emulator, enter the escape character at the
beginning of a line, followed by the rest of the command. The character prior
