On Windows XP you can use HyperTerminal as your Telnet interface, instead of entering telnet at a command prompt. Start HyperTerminal, and in the "Connect using" field, select TCP/IP (Winsock) from the drop-down menu, and specify the target IP address. HyperTerminal is a better interface than the Telnet text interface, especially if you want to capture information from a Telnet session.
