Bidirectional Telnet supports both a CAS profile Telnet connection and a TS profile menu shell.

available under this protocol.
When the attached terminal is powered on and the Enter key is pressed, a login banner and a login

timeout period can be configured through the Web Manager Ports - Physical Ports - Access form.

Web Manager, Applications - Terminal Profile Menu or from a terminal window using the
menush_cfg command. You should specify the bidirectional shell command, /bin/menush in the
