Como alguém que usou o telnet para se conectar a locutores & Antes de encontrar um cliente de lama, eu nunca ouvi falar de conexão a um caminho, e as páginas do manual indicam que não há suporte para conexão a um caminho, apenas um host.
Citando a página man do telnet, conforme aqui
open host [-l user] [ [-] port]
Open a connection to the named host. If no port number is specified, telnet will attempt to contact a TELNET server at the default port. The host specification may be either a host name (see hosts(5)) or an Internet address specified in the ''dot notation'' (see inet(3)). The -l option may be used to specify the user name to be passed to the remote system via the ENVIRON option. When connecting to a non-standard port, telnet omits any automatic initiation of TELNET options. When the port number is preceded by a minus sign, the initial option negotiation is done. After establishing a connection, the file .telnetrc in the user's home directory is opened. Lines beginning with a ''#'' are comment lines. Blank lines are ignored. Lines that begin without whitespace are the start of a machine entry. The first thing on the line is the name of the machine that is being connected to. The rest of the line, and successive lines that begin with whitespace are assumed to be telnet commands and are processed as if they had been typed in manually to the telnet command prompt.
