You can connect to the XPS server through the debug port using an SSH client. The SSH client must be installed on your machine to the SSH server.
Set up the SSH client for Linux or Mac
If you are using a Linux or Mac client, the SSH client is already built-in. This means you can just open a terminal window and run the SSH commands to connect with the SSH Server.
Set up the SSH client for Windows
If you are using a Windows client, you need to install an SSH client if it doesn't have it already. The SSH client runs as a terminal window connected to the SSH server.
OpenSSH: Newer and updated versions of Windows may have the open-source OpenSSH already installed. Windows provides OpenSSH with the latest Windows 10 (even then only starting the Anniversary Update) where they added the open-sourced version of SSH into the operating system (OpenSSH). It is still not inherently available and is part of the "Optional Features".
PuTTY: You can also download and install PuTTY. PuTTY is open-source software that provides SSH and telnet clients for Windows systems. PuTTY is available through https://www.putty.org/ (https://www.putty.org/).
