console [-aAfFsS]] [-rv] [-e esc] [-M server] [host]
console is a client command which establishes a session with the appropriate conserver daemon running on a PC with a serial connection to the console specified on the command line. When invoked console connects to the master conserver server to establish which server is physically attached to the console you wish to connect to. If the console is not on one of the master server's serial ports console drops the connection and connects to the server which is attached.
Since console does not support encryption you should use sshconsole which does and takes the same arguments.
