Accessing the Serial Ports
There are four ways to access the serial ports, depending on the protocol you configured for
that serial port (all.protocol being socket_server for telnet access, socket_ssh for ssh access,

ssh -l <Username>:<Server> <CAS hostname>
<Username> is the user configured to access that serial port. It is present either in the local
