Creating a Management Link Through the COM Port
When the COM port is configured as the IP management link (Net Link), the user
interface is also accessible via Telnet. Although not shown in the illustration
below, a LAN adapter can be connected to the COM port to provide Ethernet or
Token Ring connectivity, or an async terminal (or other VT100-compatible)
interface can be directly connected to the COM port, as well.
