Telnet Device

TelnetDevice sends commands to 3rd party products over a TCP network connection using the Telnet protocol — typically on port 23. It is used to remotely control hardware that exposes a text-based command interface.

TelnetDevices are used by the Control Layer and the Matrix Control layer.
