The default escape sequence on a serial session is ^Ec plus a function key (that is press CTRL and e keys altogether, release, then c plus the function key).

Below are the function keys and their description:

 .    disconnect                                 b   send broadcast message

 g   group info                                  i    serial port information

 l    send break per config file         s    spy read only

 w  who is on this console              z    disconnect user session 

 <cr> ignore/abort command         ?    print this message

 k   serial port(<speed> <databits><parity:n|e|o><stopbits> <flow:n|s|h>)

Example:

To send a broadcast message to all active user: ^e cb then type the message

To get serial port information: ^e ci

To disconnect the current session: ^e c.  and then on the cli prompt type exit

There is a global disconnect hotkey that can be set. This hotkey closes the entire session at once.

From WebUI: go to Managed Devices, Preferences, Session Preferences

From CLI: cd /settings/devices_session_preferences

The disconnect_hotkey should start with CTRL and up to 2 keys, for example ^kx or ^k.

 

Example:

[admin@nodegrid devices_session_preferences]# set disconnect_hotkey=^k.
