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.
[+admin@nodegrid devices_session_preferences]# commit
