How to access Freebsd OS from console of SSH? (Resolved)

[kapara]

Is it possible to do this via console or ssh when running pfsense?  I need to be able to interact with the physical devices to try and test which port provides the data needed.

Example:  How do I get access to this prompt so I can run this command.  When I go to shell I cannot directly access cuaU0.3  I get permission denied.

root@E6420:~ # cu -l /dev/cuaU0.3

Got this working.  Had to release cuaU0.3 from PPP and then was able to connect using:

cu -l /dev/cuaU0.3

~. to get out of the session.
