The TELNET Protocol
The TELNET Protocol
The TELNET protocol provides a bidirectional, byte-oriented communications facility.
The TCP/IP or IPX/SPX connection is used to transfer data and TELNET control
functions are referred to as TELNET connections.
Both ends of a connection, the TELNET client and Telserv, negotiate TELNET control
functions once the connection has been established. Control functions, which allow
either end of the connection to dynamically modify the connection characteristics, are
divided into two categories: commands and options. A command causes some action
to occur, whereas an option simply negotiates whether or not a command will be used.
For more information, see TELNET Client Commands and TELNET Commands on
page 9-1.
Modes of Operation
If you use client software from another vendor, you can interactively select the modes
of operation described below. Note that the TELNET client provided by HP does not
allow you to negotiate modes of operation.
Line Mode and Character Mode
In character mode (the default), the TELNET client immediately sends each character
you type to the remote system. In line mode, the text you type is echoed locally, then
sent to the remote host when you press the RETURN key (start and stop bits indicate
the beginning and end of the data string).
To select line mode, use the TELNET client mode command (see mode Command on
page 9-3).
Note that a TELNET client enters the mode the user specifies only if the remote host
can enter that mode.
ASCII and Binary Mode
Telserv supports both ASCII and binary transfer modes. ASCII is the default mode.
When in ASCII mode, Telserv performs end-of-line processing of incoming and
outgoing data.
As a terminal user, you can toggle between ASCII and binary modes by following these
steps:
1. Access Telserv.
Note. The interface to IPX/SPX is available on G-series systems only.
Note. These instructions assume that you are using the client software from Sun
Microsystems.
