What is Reverse Telnet Mode?
In Reverse Telnet Mode, the Telnet session is initiated from the network. The
serial device waits for the network host to initiate the connection. Typically,
Reverse Telnet Mode is used for console server applications, where a network host
Telnets to a device's console port for configuration or maintenance. TCP Server
Mode is similar in that it involves a serial device acting as a server. However, TCP
Server Mode does not convert CR/LF characters.
