Logging into a Host with telnet

Checking Your Local Terminal Conﬁguration

Before you log into a remote host with telnet or rlogin, ensure that

your local terminal conﬁguration settings are correct for the type of

remote communication you intend to perform. Two factors determine

whether you need to change your local terminal conﬁguration settings:

• The type of remote host you intend to log into.

• The type of applications you intend to run on the remote host.

Follow these guidelines if you have an HP terminal attached to an

HP 9000 computer as your local host:

• Whenever you log into a remote DEC VAX VMS host, the HP

terminal should be set to ANSI compatibility mode. Set the ANSI

terminal conﬁguration to map DEL (ASCII 127) to the backspace key

and to use the XON/XOFF protocol handshake.

• Whenever you communicate with a remote HP host, the HP terminal

should be set to HP compatibility mode. Set the HP terminal

conﬁguration to map BS (ASCII 8) to the backspace key and to use the

ENQ/ACK protocol handshake.

These terminal conﬁguration settings ensure that both screen-oriented

and line-oriented applications work properly when run on a remote host

through telnet or rlogin. Other terminal conﬁguration settings do not

need attention.

In general,

• Remote line mode applications work well over telnet or rlogin

regardless of your local terminal’s compatibility mode setting.

• Remote screen mode applications require your local terminal and the

remote host to use the same commands to control cursor movement.

• Remote block mode applications do not work over telnet or rlogin

and are not supported.

For more details, see the terminal documentation for the hosts with

which you work.
