8.3 Connecting to Another Device by Using the Telnet
Redirection Function
If the client is not connected to the remote device on an IP network, you can manage the device

from a router by using the Telnet redirection function.
The remote device can be a device that supports serial interfaces, such as a router, a switch, or
a modem.
