Configuring Ports

Chapter 5 53

Terminal Server Mode

In terminal server mode, the Digi CM unit’s serial port is configured to wait for data

from the device connected to the port. If data is detected, the Digi CM unit starts a

TCP session as a Telnet or SSH client to a pre-defined server. The server must be

defined by you before the port can be configured for a Telnet or SSH client. This

mode is used when you want to access servers on the network from a serial

terminal. RawTCP is also supported with the Terminal Server Mode.

Dial-In Modem Mode

In this mode, the Digi CM unit 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 unit 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.
