Dial-In Modem Mode
In this mode, the Digi CM assumes an external modem is attached to the serial
port and is waiting for a dial-in connection from a remote site. When a user
dials-in using a terminal application, the Digi CM accepts the connection and
displays the appropriate prompt or menu for you that logged in. Example: User
’root’ would see the command line interface (CLI), whereas the user ’admin’
would see the config menu or CLI depending on the shell for that user.
Dial-In Terminal Server
Dial-in terminal server mode is a combination of the terminal server mode and
the dial-in modem mode. In the dial-in terminal server mode, the Digi CM
assumes the serial port is connected to an external modem and is waiting for a
dial-in connection from a remote site. When you dial-in using terminal
applications, the Digi CM accepts the connection as a Telnet or SSH client to a
pre-defined server. This mode is most frequently used when you want to use
modems to access servers on a network.
