If you are using a different operating system, please refer to that operating system's built-in help or documentation for information on using or enabling the telnet client.
  1. Connect a computer directly into one of the Zoom ADSL Modem/Router’s ETHERNET ports (labeled 1, 2, 3, or 4) using an Ethernet cable.
