When LINEMODE is enabled, character processing is done on the local system, under the control of the remote system. If this fails, then telnet will revert to one of two input modes: either 'character at a time' or 'old line by line' depending on what the remote system supports. Once a connection is opened, telnet attempts to enable the TELNET LINEMODE option. If not specified, the telnet port ( 23) is used. Specifies a port number or service name to contact. Specifies a host to contact over the network. Opens tracefile for recording trace information. This option implies the -a option, and may also be used with the open command. By sending the specified name as the USER environment variable, so it requires that the remote system support the TELNET ENVIRON option. Specify user as the user to log in as on the remote system. Entering the escape character while connected causes telnet to drop to command mode. If no character is supplied, no escape character will be used. Sets the IP TOS (type-of-service) option for the telnet connection to the value tos. These codes are accepted only at the beginning of a line. A ^Z ( Control-Z) instead of a dot suspends telnet, and a ^] (Control-close bracket, the default telnet escape character) generates a normal telnet prompt. Also, the interpretation of the escape character is changed: an escape character followed by a dot causes telnet to disconnect from the remote host. In this mode, the default escape character is a tilde. Sets the initial value of the debug toggle to TRUE.Д®mulate rlogin. Use bind on the local socket to bind it to a specific local address. The username is retrieved via the getlogin system call. Currently, this sends the username via the USER variable of the ENVIRON option if supported by the remote system. This option causes the TELNET BINARY option to be negotiated on output.ДЄttempt automatic login. By default, telnet is not '8-bit clean' (it does not recognize 8-bit character encodings such as Unicode).Дisables the escape character functionality that is, sets the escape character to 'no character'.

This option causes an attempt to negotiate the TELNET BINARY option for both input and output. If telnet is invoked with a host argument, it performs an open command implicitly (see the Commands section below for details). It begins in command mode, where it prints a telnet command prompt (' telnet>'). The telnet command is used for interactive communication with another host using the TELNET protocol.
