Bidirectional Telnet supports both a CAS profile Telnet connection, and a TS profile menu shell. Both connection protocols are supported on one port, however, connections cannot be opened simultaneously.Note: The Console profile features such as data buffering, multiple users, and event notifications are not available under this protocol.When the attached terminal is powered on and the keyboard’s [Enter] key is pressed, a login banner and a login prompt is displayed.Note: If the user does not login within a configurable timeframe, the serial port returns to an idle state. The timeout period can be configured through the Web Manager Ports > Physical Ports > Access form.The administrator can build custom menus using the “Terminal Profile Menu” form accessible from 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 Web Manager, Ports > Physical Ports > Access form.
