TELNET (Telecommunication Network protocol) provides a bidirectional, text-based, interactive command-line session to a remote host over TCP port 23. It was the standard method for administrators to log into and manage UNIX servers remotely before SSH became prevalent. Because it operates as a terminal emulator over TCP/IP, it directly fulfills the requirement of a text-based connection to the ISP's UNIX server.

IPCONFIG is a local diagnostic command that displays and manages the IP configuration of the local machine, providing no remote access capability.

PING sends ICMP echo requests to test network reachability and latency; it does not provide any interactive session or remote access.

FTP (File Transfer Protocol) is used to transfer files between hosts and does not provide an interactive text-based terminal or shell session.

TRACERT traces the network route (hops) from the local machine to a destination and does not provide any remote login or terminal functionality.
