What escape sequences and pmshell menu commands are available inside a console session?

When connected to a Console Server Mode port e.g. using SSH, you are connected via portmanager's pmshell environment.

Inside pmshell and when connected to a port, there are several pmshell commands available to assist with console management.  These commands are run by typing a special sequence of characters known as an escape sequence.

Notes concerning the escape character:

• By default, the escape character is: ~
• If you are connected using the OpenSSH command line client, e.g. from Mac or Linux system, you must type a second ~ to trigger the escape, i.e.: ~~
• An alternate escape character may be set under Serial & Network -> Serial Port -> Edit/Edit Multiple Ports -> Escape Character
• The escape character must be the first character on a new line

To demonstrate, here is an escape sequence to display the pmshell command help text.

Type: <enter>~?

Shell Commands:
~b - Generate BREAK
~h - View history
~p - Power menu
~c - Port Configuration menu
~u – User sessions disconnect menu 
~m - Connect to port menu
~. - Exit pmshell
~? - Show this message

If the above help text does not display, check you are using the appropriate escape sequence.  Otherwise, the available commands are:

• Generate break: Send a serial break signal to the device on this port
• View history: Display recent TX and RX event logs for this port
• Power menu: If enabled and configured, open the power menu for power control of the device on this port
• Port Configuration menu: Display configuration menu for currently connected port
• User sessions disconnect menu: - open list of user sessions, select by number to disconnect
• Port menu: Drop back to the pmshell chooser menu to connect to another port
• Exit pmshell: Terminate this portmanager session
